The referendum to now

Ever since that fateful vote on the 23rd June 2016, the United Kingdom has been in turmoil. The pound fell , and it still has not recovered. At least in banking will leave the City of London for other, more stable shores. The housing market has come grinding to a halt, jobs all across the country are at risk, and foreign capital coming into the UK has dropped dramatically. But at least warehouses are thriving while everyone stocks up, like the end of the world is coming!

So how did we get here? What is the real cause of all of this uncertainty? We have released that deals with how leaving the EU became such a big issue in the UK. There is also a .

Why did the British people vote for Brexit?

For those of you that aren't British, and indeed some of you who are, it may be difficult to understand why a majority of British people chose to leave to EU. It would be impossible to create a full list of the reasons why people voted out, but it can be broken down into the two most important issues voters cited when questioned on the day of the vote, British sovereignty (32%) and immigration (48%). There is also the idea that the campaign dedicated to keeping the UK in the EU (Remain) did not do enough to sway public opinion against the movement for Brexit (Leave).

Brits make no secret, and are sometimes proud, of their self-imposed distinction from the continent. The British often speak of "Europeans" like they themselves are not European, that the Channel somehow makes their fair isles a continent of their own. This distinction is not just a linguistic quirk but a political one as well. shows that the British don't consider themselves very European, having always come among the countries least likely to say they are attached when answering "How attached you feel to Europe?" (The UK came 4th from bottom in both Autumn 2014 and Autumn 2015.) Why?

It is difficult to say; maybe that thin strip of the sea called the Channel really does make all the difference, geographically speaking? Maybe this ideology is left over from the Empire, where Britain ruled over an area greater than Africa? Who is to say, but the fact is that the British do not consider themselves European.

One of these may be the reason why Brits do not like the imposition of laws from Brussels. The British people have a long history of the ideas of liberty and sovereignty, dating back to the Magna Carta but coming to a head during the English Civil War, and the perception that the UK is not in control of its laws is seen as a great affront by some. That those EU laws have only the ultimate authority in areas that all its nations have agreed to, was perhaps not talked about by the Remain campaign.

There is also the idea that the EU is run by bureaucrats that cannot be elected and, despite having total control over UK law, never pass any laws. Although they are not elected, the EU Commission can be dissolved at any time by the EU Parliament. And it is true that every nation in the EU has a veto, which they use to ensure they are not getting the short end of the stick. That they sometimes use it for more selfish reasons is true; however, no one is saying the EU is perfect.

The most significant reason voters said was the influx of immigrants. Although immigration has been occurring in the UK on a large scale since the beginning of the post-war period, the amount has increased significantly since the end of the 1990s. There was a prevalent idea that immigrants were coming over to the UK just to use the NHS and the school systems. This was enough of an issue for David Cameron, the previous Prime Minister, to renegotiate the terms of UK membership to the EU in 2015-16, putting in place a four-year wait until EU immigrants could use such systems.

It is also worth noting that noticed that Leave voters were the majority in 94 % of places that saw over a 200 % increase in foreign-born population between 2001 and 2014, i.e. that people were more in favour of Leave when the increase in immigration was more noticeable. This, coupled with the refugee crisis that many people saw as a "hoard of refugees that are coming to our homeland that the EU is mandating we accept." This last point was, expectedly, exaggerated by the right-wing media to become a point of fear for the average person, as the UK accepted very few refugees when compared to, say, Hungary or Sweden. It is also possible that some people believed that leaving the EU would reduce the number of immigrants from non-EU countries, something which would not occur.

So, why was the Remain campaign so weak? Maybe the mentality was that people would choose the evil they know rather than the evil they don't, that the Leave argument was so weak that they didn't need to do anything. Labour leader Jeremy Corbyn only appeared to give lip service to Remain. The only thing necessary for the triumph of evil is for good men to do nothing.

The future of Brexit

Although which future the UK is going down is murky, there are only 4 available options and it all comes down to Ireland.

Before we look to the future, we must understand the past. The English have had an interest in Ireland since the Normans invaded in 1169. After a few centuries of on-and-off rule, the English kings finally decided to bring Ireland under more centralised control, and with this control came the spreading of their newfangled religion, Protestantism. Land from rebellious lords was confiscated and given to English Protestants, to both cement control and spread the word of God. This system, known as the Plantations, was most successful in northern Ireland, known traditionally as Ulster. Tensions strained for many centuries, and centuries of repression cumulated in the Anglo-Irish War, fought from 1919-1921.

In the middle of the war, Parliament passed the Government of Ireland Act 1920, which, with the aim "to provide for the better government of Ireland", split the island between the predominately Protestant and industrialised north and the Catholic and agrarian south. At the conclusion of the war, the British sued for peace, and the subsequent Anglo-Irish Treaty created the Irish Free State, a semi-autonomous Dominion of the Crown, much like Canada and Australia at the time. As part of the treaty, the Northern Irish Parliament, set up as part of the Government of Ireland Act 1920, would be given the option to opt out of the Free State. It did so on 7 December 1922, the day after the Free State was established, and remains an integral part of the United Kingdom to this day.

All was not well though. The Catholic minority in the north was subject to political and social persecution in the ensuing years. Their peaceful protests were put down brutally by the police, leading to the violence escalating, which broke into the Troubles, a guerrilla and bombing campaign between Nationalists, Unionists and the British Army. The Troubles continued for three decades and were finally ended by the Good Friday agreement, which amongst other things, established cross-border cooperation between the North and South.

The fact that the Irish border is the only land border between the UK and EU is what's making Brexit so difficult. Between this border issue, the wish to keep the Union whole, and the desire for a maximum Brexit, we come to our four futures:

1. A hard border between the Republic of Ireland and Northern Island, a.k.a. No Deal Brexit - In order to ensure that full and total liberation from the EU is achieved, a hard border is put up between the two Irelands; all goods and people coming through must be checked and the appropriate tariffs paid for them (the goods that is). This leaves the UK completely free in every way from the EU, but what will this mean for the two Irelands? Smuggling will no doubt crop up around the border, as people look to avoid the tariffs and exchange rate between the pound and euro. The time lost waiting at the border will also be a big hit to the economy of both countries, with 25 % of the Republics exports going to the UK and 5.3 % the other way. And what about the Good Friday agreement? Nothing stirs up old feelings of resentment like being turned away at the border when you go to see your family. Would peace reign, or would violence flare up again?

2. No border in Ireland, but a border in the Irish Sea - No border is erected between the two Irelands, leaving Northern Ireland in the EU customs union while the rest of the UK leaves it. This means that tariffs and passport checks occur either as goods and people leave Northern Ireland or arrive at the rest of the UK. The UK is allowed to make trade deals with the rest of the world. Maximum Brexit is still achieved but at the likely cost of Northern Ireland. As intra-Ireland trade can still occur unhampered, but trade between the North and the rest of the UK is slow, Northern Ireland becomes closer and closer to the Republic and further and further from the Union with each passing year. The Good Friday agreement stipulates that unification can occur if both sides want it, and with each decade, this looks more likely.

3. No hard border anywhere, but no maximum Brexit - Trade and people can flow unhindered from Ireland to Northern Ireland to the rest of the UK, at the cost of concessions on the nature of Brexit. The UK remains mostly in the single market, the free movement of people still occurs, and some EU laws still apply. People ask themselves, "Why did the UK go through all this trouble just to stay in the EU, mostly?"

4. The UK does not leave the EU at all - Either a second referendum is held, or discussions with parliament go nowhere, the UK keeps asking the EU for extensions on Article 50, and the EU keeps granting them. This continues until one of the options above occurs, or one side asks the other if Brexit can stop. Instability and unpredictability are the orders of the day for the entirety of this process, and the many businesses leave British shores due to this. People ask themselves, "Why did the UK go through all this trouble just to stay in the EU?"

The deal that Johnson struck with the EU closely resembles option 2 - free trade will be able to flow between the Irelands, and anyone sending goods to Northern Ireland will have to pay import taxes. These taxes can be refunded if the goods are sold in Northern Ireland, but as an additional expense it is still a barrier to trade.

Lost potential and how that money could be spent

Uncertainty is bad for business. Why would you order goods from a country that might not be able to get them to you or for the cost to double before they get to you? Even with the deal being signed, this is the current situation in the United Kingdom. Before 2020, the Centre for European Reform estimated that the UK was . In early 2020, Bloomberg Economics published their findings, predicting that another .

Why the change? Quite simply, uncertainty changes with time and circumstance. Before 2020, people could still trade with the UK in a free market, whereas with the UK's withdrawal being imminent, tariffs begin going up. Therefore people are significantly less likely to do business with the UK until a trade deal can be reached. This number may change in the future, but until then, we will use it as the annual loss in GDP post-2020.

What could we do with this money? We have given a few serious and a few less serious things that this money could have been spent on to give you an idea of the social, environmental and infrastructural ills that could have been fixed.

Brexit timeline

To give a brief history, the timeline below begins from Theresa May's election to head of the Conservative Party (and therefore Prime Minister) to the current day:

• 20/7/2016 - May visits Angela Merkel in Berlin, stating that the UK wishes to keep the "closest economic links" with the EU. May also said she would not invoke Article 50 (the means by which a country can leave the EU) during 2016.
• 17/1/2017 - May outlines the aims of Brexit in a speech from Downing Street. This included, the UK's departure from the single market (a necessity based on her stance during the Conservation leadership election), leaving the customs union while still wanting tariff-free trade with the EU, the desire to avoid a “hard border” between Northern Ireland and the Republic of Ireland, and the need for some kind of transitional period when Brexit kicked in, amongst other things.
• 2/2/2017 - The White Paper is released by the government, formalising what May said in her 17/1/2017 speech.
• 29/3/2017 - Article 50 is invoked, meaning the UK will leave the EU in exactly two years.
• 18/4/2017 - May calls a snap election, something she had previously ruled out, with the aim of strengthening her hand when it comes to Brexit negotiations.
• 8/6/2017 - The general election is held. The Conservatives lose 13 seats and with that their majority. A hung parliament occurs until the Tories form a coalition with the DUP (Democratic Unionist Party).
• 19/6/2017 - Brexit Secretary David Davis arrives in Brussels, marking the beginning of negotiations for a deal.
• 22/9/2017 - In Florence, May gives her speech on the nature of the transitional period, and promises to continue funding EU security and science projects.
• 19/3/2018 - The transition period was agreed, and a document is published showing 75% of the deal has been agreed upon.
• 14/11/2018 - Text of the withdrawal agreement is published, including provisions for a “backstop” with regards to the Irish border.
• 15/11/2018 - The Brexit Secretary, Dominic Raab and the Work and Pensions Secretary, Esther McVey, resign over the deal.
• 25/11/2018 - The EU endorses the Brexit deal.
• 12/12/2018 - May survives a vote of no confidence.
• 15/1/2019 - The House of Commons votes down the Brexit deal, 432 to 202.
• 11/3/2019 - Deal is renegotiated with the EU, making sure the that the backstop is temporary.
• 12/3/2019 - Second vote on the agreement is voted down, 391 to 242.
• 13/3/2019 - The Commons voted against leaving the EU without a deal in a non-binding agreement, 312 votes to 308.
• 14/3/2019 - Motion passes by 412 to 202, delaying the Article 50 negotiating period.
• 18/3/2019 - Speaker Bercow says May cannot have a third vote without significant changes, triggering a constitutional crisis.
• 20/03/2019 - May asks EU Council President Donald Tusk for an extension on Brexit. Extension is granted to, at the earliest, 12th April.
• 25/03/2019 - Parliament, by 27 votes, grants itself more power to decide the outcome of Brexit.
• 29/03/2019 - The day the UK should have left the EU.
• 30/03/2019 - Despite promising to resign if the bill passed, May's third 'meaningful vote' fails, 344 votes to 286.
• 03/04/2019 - MPs pass, by one vote, a bill to force May to ask the EU for a further extension.
• 11/04/2019 - EU grants the UK a further extension on Brexit, until 31 October. Spooky.
• 23/05/2019 - European Parliamentary elections are held in the UK. The Brexit Party, headed by Farage, comes out on top with 29 of the 73 seats (39.7% of the seat). The remaining seats all hold pro-EU positions from across the political spectrum.
• 24/05/2019 - Theresa May announces that she will resign as leader of the Conservative Party, and therefore as Prime Minister, on 7 June 2019. This triggers another leadership contest within the Tory Party.
• 23/07/2019 - Former Foreign Secretary Boris Johnson, is elected to lead the Conservative Party and therefore the country. He plans to renegotiate the Brexit deal devised by May's government, but states that the UK will be leaving the EU on 31 October, even if MPs cannot reach an agreement on any deal, i.e., the UK will leave with no deal.
• 28/08/19 - After attempting renegotiations with the EU, Boris Johnson sends out a letter to MPs stating that he wishes to prorogue parliament. This means that the parliamentary session would end on 12 September, and begin again on 14 October. Johnson likely wishes to use this break before the new Brexit Day to limit the amount of time MPs have to vote on another Brexit extension.
• 03/09/19 - The Benn Bill passes, requiring the PM to seek an extension to Brexit if the Commons does not approve either a deal or no-deal by 19/10/19.
• 24/09/19 - The Supreme Court rules that the PMs decision to suspend Parliament was unlawful.
• 02/10/19 - The Government publishes a new plan to deal with the Irish border. It states that, due to the entire UK leaving the EU's customs union, a new customs border between Northern Ireland and the Republic of Ireland would have to be constructed. However, as many custom checks as possible being done at trader's premises, to minimise the border's impact. The smallest traders would also be exempt from any customs procedures.
• 17/10/19 - A new deal is agreed upon by the UK and the EU. Northern Ireland is set to have a different customs arrangement with the EU than the rest of the UK, which the DUP reject.
• 19/10/19 - In a rare Saturday sitting of Parliament, MPs preempt Johnson's vote on the current deal by introducing and passing the Letwin amendment, which states that the government will only vote on the new deal once legislation to enact it was law. This is aimed at preventing the derailing of the legislation to implement the deal, which would lead to a no-deal Brexit. Johnson was then forced to write to the EU asking for an extension until 31 January 2020, a letter which he did not sign. He did, however, sign a letter asking the EU for support for his efforts to get a withdrawal without an extension.
• 21/10/19 - The Speaker refuses a new vote on the new deal, citing that the motion is still the same "in substance". The government introduces the EU (Withdrawal Agreement) Bill, which aims to make the Brexit deal law.
• 22/10/19 - The EU (Withdrawal Agreement) Bill passes, but is not fast tracked, meaning that Johnson will not be able to get his deal through the Commons by 31 October.
• 28/10/19 - The EU agrees to an extension until 31 January.
• 29/10/19 - The Government introduces an Early Parliamentary General Election bill, which sets a general election for 12th December.
• 6/11/19 - Parliament is dissolved.
• 12/12/19 - The Conservatives win the general election with an 80-seat majority.
• 20/12/19 - Johnson's deal is voted on again, this time passing.
• 31/01/19 - The UK leaves the EU.
