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 agreement covers issues such as money, citizens` rights, border agreements and dispute resolution. It also includes a transition period and an overview of the future relationship between the UK and the EU. It was published on 14 November 2018 and was the result of the Brexit negotiations. The agreement was approved by the heads of state and government of the other 27 EU countries and by the British government led by Prime Minister Theresa May, but it faced opposition from the British Parliament, which needed approval for ratification. The approval of the European Parliament would also have been necessary. On January 15, 2019, the House of Commons rejected the withdrawal agreement by 432 votes to 202.  The House of Commons again rejected the agreement by 391 votes to 242 on 12 March 2019 and rejected it a third time, on 29 March 2019, by 344 votes to 286. On 22 October 2019, the revised withdrawal agreement negotiated by Boris Johnson`s government approved the first phase in Parliament, but Johnson halted the legislative process when the accelerated approval programme failed to receive the necessary support and announced his intention to declare a general election.  On 23 January 2020, Parliament ratified the agreement by adopting the withdrawal agreement; On 29 January 2020, the European Parliament approved the withdrawal agreement.
It was then concluded by the Council of the European Union on 30 January 2020. The UK has launched the formal process of withdrawal negotiations by formally announcing the European Council`s intention to leave the EU. After an unprecedented vote on 4 December 2018, MEPs ruled that the UK government was not respecting Parliament because it refused to give Parliament full legal advice on the consequences of its proposed withdrawal terms.  The focus of the consultation was on the legal effect of the “backstop” agreement on Northern Ireland, the Republic of Ireland and the rest of the United Kingdom with regard to the CUSTOMS border between the EU and the United Kingdom and its consequences on the Good Friday agreement that ended the unrest in Northern Ireland, including whether the United Kingdom would be insured , in line with the proposals, to be able to leave the EU in a practical sense. 467The objective of Appendix 3 is to provide for the “do not reduce” obligation and the necessary provisions for the “dedicated mechanisms” provided for in Article 2, paragraph 1, of the Protocol on Ireland and Northern Ireland. This article stipulates that there must be no reduction in rights, guarantees and equal opportunities, as provided for in the “Rights, Protections and Equal Opportunity” chapter of the 1998 Belfast Agreement in Northern Ireland following the UK`s withdrawal from the EU, including protection from discrimination under the provisions of EU law in Appendix 1 of the Protocol. This must be implemented through “dedicated mechanisms.” On 20 December 2019, after the Conservatives won the 2019 British general election, the House of Commons passed second reading of the withdrawal agreement with a 358-234 lead. Following the amendments proposed by the House of Lords and the ping-pong between the two houses, the bill was granted royal approval on 23 January 2020, allowing ratification on the British side.  The most important elements of the draft agreement are:  55The bill therefore contains provisions allowing the government to take the necessary steps to comply with the protocol complementing these general provisions.
