Many of the effects of Brexit depended on the UK withdrawing through a withdrawal agreement or before the ratification of a “Non-Deal” Brexit agreement.  The Financial Times reported that there were some 759 international agreements in 168 third countries in which the UK would no longer have participated after the EU withdrawal.  On 17 October 2019, the UK and the EU agreed on the terms of the UK`s exit (Brexit) and a transitional period until 31 December 2020. The blockade was resolved after the parliamentary elections that followed in December 2019. In this election, the Conservatives, who advocated a “revised” withdrawal agreement under Boris Johnson, won a total majority of 80 seats. After the December 2019 elections, the British Parliament finally ratified the withdrawal agreement. The UK left the EU at 11 .m GMT on 31 January 2020. This is the beginning of a transition period due to end on 31 December 2020, during which the UK and the EU negotiate their future relations.  During the transition, the UK remains subject to EU law and is part of the EU customs union and internal market. However, it is no longer part of the EU`s political bodies or institutions.   The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments fit about 5% of the text.
 Exit from the European Union is governed by Article 50 of the Treaty on european Union. Originally designed by Lord Kerr of Kinlochard, it was introduced by the Lisbon Treaty at the request of the United Kingdom. [Citation required] The article stipulates that each Member State can withdraw “in accordance with its own constitutional requirements” by informing the European Council of its intention to do so.  The notification triggers a two-year negotiating period during which the EU “must negotiate and conclude an agreement with [the withdrawal state] defining the terms of its withdrawal within the framework of its future relations with the European Union”.  If no agreement is reached within two years, accession will end without agreement, unless all EU Member States, including the Withdrawal Member State, are unanimously renewed.  On the EU side, the agreement must be ratified by the European Council and the European Parliament by qualified majority.  The European Union and the United Kingdom conclude a draft withdrawal agreement. In October 2019, the British Parliament passed the Early Parliamentary General Election Act, which circumvented the Fixed Parliament Act 2011 and declared a general election for 12 December 2019.  In the election, Boris Johnson`s campaign focused on “creating Brexit,” and the Conservative Party won a majority of 80 seats in Parliament.  The government then introduced a bill to ratify the withdrawal agreement. It passed its second reading in the House of Commons by a vote of 358 to 234 on 20 December 2019 and came into force on 23 January 2020 as the European Union Act (Withdrawal Agreement) 2020.  The Brexit withdrawal agreement, officially titled the United Kingdom`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 (UNITED Kingdom) which sets the conditions for the UK`s withdrawal from the EU and Euratom.
