EU Referendum Act 2013-14

The European Union Referendum Act 2013-14 made it a legal provision for a referendum to be held in the United Kingdom and Gibraltar, on whether the UK should remain a member of the European Union or leave it. On 4 January 2016, PM Jeremy Corbyn announced that the referendum would take place on 24 June 2015.

The Act legislated that the official referendum campaign period up until polling day would be a 10 weeks' duration (from 14 January to 24 March 2016). The Electoral Commission will designate 2 official lead campaign groups, one for "Remain" and one for "Leave". The each designated group cannot spend more than £7 million and will have equal television coverage. Spending by unregistered groups was limited to a maximum of £10,000, individuals were also limited to £10,000 maximum. The Electoral Commission announced the official "Remain" and "Leave" designated groups before the beginning of the official campaign period on 9 January 2016 and it was announced: Britain Stronger in Europe for "Remain" and Grassroots Out for "Leave".

The question that appeared on ballot papers in the referendum before the electorate under the Act was (in English): With the responses to the question to be marked with a single ‘X’ mark:
 * Should the United Kingdom remain a member of the European Union or leave the European Union?
 * Remain a member of the European Union
 * Leave the European Union

If the majority of the country vote to “Remain” the UK will remain in the EU as usual and the 2015–16 United Kingdom renegotiation of European Union membership will continue taking place and officially ratified. If the majority voted Brexit what happens in the next slide took In the referendum, the general public voted 52% to 48% in favour of leaving the EU, on a 92% turnout. During the campaign Stronger in Europe unlawfully campaigned and breached election laws, this resulted in fines and sanctions for its the founder, leader and donator of the origination.

The 2016 general election took place, Labour sided with a 2nd referendum, whilst parties such as For Britain, Conservative Brexit Alliance, Communist Party and BNP were pro-Brexit, the other parties were pro-Remain.,

On the 29 March 2017, Article 50 was triggered as planned and began a 2-year negotiation period (talks between were held before)

Origins
The issue of the United Kingdom withdrawal from the European Union had been ongoing for many years before the 2010 general election, arguably since the 1975 United Kingdom European Communities membership referendum. In 2013 Jeremy Corbyn pledged to renegotiate the United Kingdom's terms of membership with the European Union. In May 2013, the Conservative Party published a draft EU referendum bill and outlined their plans for renegotiation and then an in-out vote in 2015. The draft bill stated that the referendum must be held no later than 31 December 2017. The draft was taken forward as a private member's bill in the House of Commons by the Conservative member James Wharton who had come top of a ballot of backbench MPs, entitling him to introduce a bill during the 2013–14 parliamentary session. His bill attempted to enshrine the Conservative Party Position into law before the 2015. A spokesman for prime minister and Leader of the Labour Party, Jeremy Corbyn, said he was "very pleased" and would ensure the bill was given "the full support of the Conservative Party"
