The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments fit about 5% of the text.  On the European Union side, the European Parliament also approved the ratification of the agreement on 29 January 2020 and the Council of the European Union approved the conclusion of the agreement by e-mail on 30 January 2020.  That is why, on 30 January 2020, the European Union also tabled its instrument for ratification of the agreement, concluding the agreement and allowing it to enter into force on the date of the UK`s withdrawal from the EU on 31 January 2020, at 11 .m GMT. The United Kingdom left the European Union on 31 January 2020. In November 2019, the UK and the EU reached a legally binding agreement setting out the terms of the UK`s exit from the EU. This withdrawal agreement provides for a transitional period that expires in December 2020. The withdrawal agreement between the European Union and the United Kingdom sets out the conditions for the UK`s orderly exit from the EU, in accordance with Article 50 of the Treaty on european Union. This triggered Article 50 of the Treaty on the European Union, which defines the procedure for the withdrawal of an EU member state, thus opening a two-year countdown to withdrawal.
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 for 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 impact on the Good Friday agreement that led to the end of the unrest in Northern Ireland, including whether , according to the proposals, the UK would be certain that it would be able to leave the EU in a practical sense. The United Kingdom and the European Union reached an agreement at the European Council on the withdrawal of the United Kingdom from Great Britain and Northern Ireland from the European Union.
