On 15 January 2019, Parliament rejected the Government's Withdrawal Agreement by 432 votes to 202. The Opposition has tabled a no confidence motion that will be debated today (16 January 2019). Theresa May announced that she will begin an engagement process with MPs on issues which would allow Parliament to support the Withdrawal Agreement before further talks with the EU. The Government is then likely to return to Parliament with another version of the Withdrawal Agreement (including additional clarifications/concessions from the EU, in particular, on the Irish backstop arrangements).
We expect the Government to ‘table’ a motion under section 13 of the EU Withdrawal Act by next Monday (following Dominic Grieve's controversial amendment last week to a business motion). This motion would be amendable and the Commons might ask the Government to renegotiate with the EU or hold a second referendum – see "A different deal" below.
If the Government's Withdrawal Agreement is subsequently passed, the Government would introduce the European Union (Withdrawal Agreement) Bill. The UK would leave the EU on the 29 March 2019 when an (extendable) transition period would commence and last until 31 December 2020 (during which time the UK would remain in the Single Market/Customs Union, with all EU law applying).
No-deal Brexit
The legal default outcome of the European Union Withdrawal Act 2018 (EUWA) is Brexit without a withdrawal deal on 29 March 2019. If there is no-deal (and Article 50 is not extended or revoked), then there will be no transition period and at 11.00 p.m. (UK time) on 29 March 2019, the UK will leave the EU. In the absence of the Government changing course or Parliament being able to find a majority for an alternative solution which it can then write into law, no-deal will prevail.
A ‘no-deal’ outcome does not necessarily mean the end of negotiations on withdrawal arrangements, as a negotiation outside of the Article 50 process could take place covering key issues of mutual concern. Such a "bare-bones" deal (or deals) could even result in a last minute transition period to avoid the "cliff edge" scenario on 29 March 2019, in exchange for some or all of the UK promised payment of c.£39bn to the EU.
Once the UK leaves the EU, formal negotiations on the long-term future UK-EU relationship will start under Article 218 of the What Treaty on the Functioning of the European Union.
Alternatives?
The Government's defeats in the House of Commons last week suggest that Parliament may seek to prevent a no-deal Brexit, possibly by taking control of the Parliamentary schedule. How this could be achieved and what the outcome would look like is not yet clear. A few possibilities are:
A different deal: When Theresa May returns to Parliament (which she is required to do by next Monday), the motion tabled will allow amendments, which could mean MPs putting forward an alternative plan. It is reported that some MPs (led by Dominic Grieve and Oliver Letwin, and aided by the Speaker, John Bercow (contrary to the advice of his clerks)), are seeking a way to seize control of business in the Commons, so that backbench motions would take precedence over government motions – reversing the usual convention that the Government controls the parliamentary agenda.
This is significant as, up to this point, Conservative "Remainer" rebels could only block a Government decision to pursue the default position of no-deal in the EUWA by supporting a no-confidence vote to bring down the Government. An up-ending of parliamentary procedure would allow Remainer rebels to act on their alternative Brexit plans, which they could call to a vote and make law.
Under these circumstances, it is understood that MPs could prevent a no-deal Brexit, and acting through the parliamentary liaison committee (which is dominated by Remainers by a margin of 27 to nine) could come up with an alternative proposal which would have to carry a Commons majority. This would be likely to be closer to a "softer" Norway/EEA type deal. The 27 EU member states would have to agree to any such deal, however.
The loss by the Government of control over legislation would have serious repercussions for its stability and would move the country closer to a General Election (whatever the outcome of the confidence vote today).
A second referendum: A second referendum would require legislation in Parliament to agree the question and logistics, complying with the Political Parties, Elections and Referendums Act 2000. This would require a delay to Brexit to be agreed by the 27 EU member states. There does not currently appear to be a Parliamentary majority in favour of a second referendum.
Delay: The timeline for Brexit can be delayed, following a request from the UK and agreement by the 27 EU Member States.
No Brexit: The European Court of Justice agreed that the UK could unilaterally withdraw the Article 50 notification by way of an "unequivocal and unconditional decision". This would likely need Parliamentary approval. This option would be politically very damaging for the Conservative Party and would be likely to collapse the Government, so is improbable.
