Brexit

Brexit timeline at a glance

What’s happened so far?

June 2016: EU Referendum. Across the UK as a whole, the vote to leave the European Union won by 51.9% to 48.1% voting to remain. In Wales, the leave vote was 52.5%.
29 March 2016: UK invokes Article 50 of the Treaty on European Union
19 June 2017: Brexit negotiations talks begin between the UK and the EC.  Any deal will need approval from at least 20 countries with 65% of the population.
25 November 2018: The Withdrawal Agreement was endorsed by the European Council.
15 January 2019: The Prime Minister loses the ‘Meaningful Vote’ and the Leader of the Opposition tables a motion of no confidence in the Government.

What Next?

2019

29 January: MP’s to vote on plan B of the withdrawal agreement, and amendments to the process for agreeing a deal, including an extension of the Article 50 process.
February 2019: MPs to vote on the deal in the House of Commons.  This could be repeated if necessary to win a meaningful vote, provided significant changes are made. Potentially, MP’s could agree:

  • To leave the EU without a deal
  • To seek an extension of Article 50
  • To hold another referendum
  • To make a final effort at negotiations
26 February: The proposed deadline for the government to win approval for its deal, under the Yvette Cooper amendment that will be voted on in late January. If a meaningful vote is not secured, MPs would be given a vote on whether to extend Article 50 to a date of their choosing (possibly the end of June, to fit with the schedule of European Parliament elections).
21 – 22 March: The final EU summit that the UK is expected to attend as a member of the EU
29 March: ‘Brexit Day’ – when the UK is due to leave the EU

Any Brexit deal must be approved by the European Parliament in a plenary vote. EU member states must also give the deal final approval in a ministerial meeting before it can take effect.

Negotiations can continue if all 27 leaders in the European Council agree.

If agreement is reached, a two year transition period will take place until December 2020 where some EU rules will remain, but the UK can negotiate its own trade deals.

23-26 May: Elections for the European Parliament in 27 EU countries (the UK will no longer be represented in the parliament)

2020

31 December:  Last date of the transition period. However, this could be extended to December 2022.
