At the end of November 2018, May presented to the House of Commons a draft agreement on future relations with Europe after concluding 17 months of negotiations with the EU.  As a result, the first use of the judicious vote was scheduled for December 11, 2018.  Following the success of Letwin`s first amendment, indicative votes were held on 27 March on the Brexit options favoured by Parliament. Eight proposals were voted on, eight of which failed. The most important elements of the draft agreement are: The 2019 revisions have also adapted elements of the political declaration and replaced the word “appropriate” with “appropriate” with respect to labour standards. According to Sam Lowe, a trade fellow at the Centre for European Reform, the amendment excludes labour standards from dispute resolution mechanisms.  In addition, the Equal Competition Mechanism has been postponed from the legally binding withdrawal agreement to the political declaration, and the line of the political statement that “the United Kingdom will consider taking into account alignment with trade union rules in the relevant areas” has been removed.  The reception of the agreement in the House of Commons ranged from cold to hostile, and the vote was delayed by more than a month. Prime Minister May has received a motion of no confidence within her own party, but the EU has refused to accept further changes. The second (Amendment 20) concerns the knowledge of the Sewel Convention, which guarantees that the British Parliament cannot legislate on decentralised issues without the agreement of the de decentralised legislator.
MEPs voted by 239 votes in favour and 235 against, resulting in the amendment. After voting on the third vote and the approval of the Cooper-Letwin Act at third reading by 313-312, May and her cabinet considered the possibility of bringing the withdrawal agreement back to Parliament for a fourth vote.  In mid-May, May said she would present the withdrawal agreement to Parliament in the first week of June.  Due to massive opposition to the new agreement, May postponed publication from 24 May to 4 June and subsequently resigned as Prime Minister.  Six Labor members voted for the bill – Sarah Champion, Rosie Cooper, Jon Cruddas, Emma Lewell-Buck, Grahame Morris, Toby Perkins. Here is Lewell-Buck`s speech, in which she says she decided with a heavy heart that she could not vote with the Labour Party. Immediately after the announcement of a revised withdrawal agreement on October 17, 2019, Labour, the Liberal Democrats and the DUP said they could not support the new agreement.  The Northern Ireland Protocol, known as the Irish Backstop, was an annex to the November 2018 draft agreement outlining provisions to avoid a hard border in Ireland after the UK`s withdrawal from the European Union. The protocol provided for a provision of the safety net to deal with the circumstances in which satisfactory alternative arrangements were to come into force at the end of the transition period. This project has been replaced by a new protocol that will be described as follows. On 22 October 2019, the House of Commons agreed, by 329 votes to 299, to give a second reading to the revised withdrawal agreement (negotiated by Boris Johnson earlier this month), but when the accelerated timetable it had proposed did not receive the necessary parliamentary support, Johnson announced that the law would be overturned.
  The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments amend about 5% of the text The agreement also provides for a transitional period that will last until 31 December 2020 and can be extended once by mutual agreement. During the transitional period, EU legislation will continue to apply to the UK (including participation in the European Economic Area, the internal market and the customs union) and the UK will continue to contribute to the EU budget, but the UK will not be represented in EU decision-making bodies.
