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.  On 15 November 2018, the day after the agreement was presented and the support of the British government cabinet, several members of the government resigned, including Dominic Raab, Secretary of State for leaving the European Union.  The agreement defines goods, services and related processes. Any provision of goods or services legally put on the market before leaving the EU may be made available to consumers in the UK or in the EU Member States (Article 40-41). 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. 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. 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 withdrawal agreement also contains provisions for the United Kingdom to leave the Convention setting the status of European schools, with the United Kingdom bound by the Convention and accompanying regulations on accredited European schools until the end of the last academic year of the transition period, i.e. at the end of the spring semester 2020-2021.
 On 15 January 2019, the House of Commons voted with 230 votes against the Brexit withdrawal agreement, the largest vote against the British government in history.  The government may survived a vote of confidence the next day.  On March 12, 2019, the House of Commons voted 149 votes against the agreement, the fourth-biggest defeat of the government in the history of the House of Commons.  A third vote on the Brexit withdrawal agreement, widely expected on 19 March 2019, was rejected by the House of Commons spokesman on 18 March 2019, on the basis of a parliamentary convention of 2 April 1604, which prevented British governments from forcing the House of Commons to vote several times on a subject already voted on by the House of Commons.    An abbreviated version of the withdrawal agreement, in which the annex political statement had been withdrawn, consisted of the test of “substantial amendments,” so that a third vote was held on 29 March 2019, but was rejected by 58 votes.
