Complex negotiations were concluded in October 2019 with a withdrawal agreement and a political declaration paving the way for an ordered withdrawal on 31 January 2020. On 3 February 2020, the European Commission recommended that the Council begin negotiations for a new partnership with the UNITED Kingdom. 4. The following part (Articles 126-132) contains provisions relating to the transition period that extends to the end of 2020 and is necessary to move from withdrawal to future relations. The transitional period involves extending the application of existing EU legislation. The only important exception is that Britain will no longer be part of the EU`s institutions and bodies and will no longer participate in EU decision-making. The EU and the UK have reached an agreement on the withdrawal agreement with a revised protocol on Ireland and Northern Ireland (abolition of the “backstop”) and a revised political declaration. On the same day, the European Council (Article 50) approved these texts. The agreement was revised as part of the Johnson Department renegotiation in 2019.
The amendments fit about 5% of the text.  The Brexit withdrawal agreement, officially titled the Uk`s withdrawal agreement from great Britain and Northern Ireland from the European Union and the European Atomic Energy Community, is a treaty signed on 24 January 2020 between the European Union (EU), Euratom and the United Kingdom (Uk) which sets the conditions for the UK`s withdrawal from the EU and Euratom. The text of the treaty was published on 17 October 2019 and is a renegotiated version of an agreement published six months earlier. The previous version of the withdrawal agreement was rejected three times by the House of Commons, leading Queen Elizabeth II to accept Theresa May`s resignation as Prime Minister of the United Kingdom and appoint Boris Johnson as the new Prime Minister on 24 July 2019. The idea behind the transition period is to give some air to breathe during further negotiations between Britain and the EU. The British Parliament approved the draft agreement by adopting on 23 January 2020 the implementing laws (the 2020 Withdrawal Agreement Act) of the European Union (withdrawal agreement). Following the signing of the agreement, the UK Government adopted and tabled the UK`s ratification instrument on 29 January 2020.  The agreement was ratified by the Council of the European Union on 30 January 2020, after approval by the European Parliament on 29 January 2020. The UK`s withdrawal from the EU came into force on 31 January 2020 at 11 .m GMT, when the withdrawal agreement came into force in accordance with Article 185.
At the request of the United Kingdom (Article 50), the European Council has twice agreed to extend the Article 50 period, paragraph 3 of the TUE (for the first time on 21 March 2019, until 22 May 2019, if the House of Commons approves the withdrawal agreement until 29 March 2019 and then 10 April 2019 until 31 October 2019). 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.
