10.Am 28 February 2018, the European Commission published the first draft withdrawal agreement between the European Union and the United Kingdom, in which the December joint report was implemented in accordance with the agenda. On 19 March, an amended text was published, highlighting the areas of concordance and discordance using green, yellow and white coding9. This triggered Article 50 of the Treaty on the European Union, which defines the procedure for the withdrawal of an EU Member State, with the opening of a two-year countdown. 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 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 its 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.  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. Prime Minister May has received a motion of no confidence within her own party, but the EU has refused to accept further changes.
On 6 September 2020, the Financial Times reported that the UK government was considering drafting new laws to circumvent the protocol of the Northern Ireland Withdrawal Agreement.  The new law would give ministers the power to determine which state aid should be notified to the EU and to define which products at risk of being transferred from Northern Ireland to Ireland (the withdrawal agreement stipulates that in the absence of a reciprocal agreement, all products are considered vulnerable).  The government defended this approach and stated that the legislation was in accordance with protocol and that it had only „clarified“ the volumity in the protocol.  Ursula von der Leyen warned Johnson not to violate international law and said that the implementation of the withdrawal agreement by Britain was a „precondition for any future partnership“.  On 8 September, the Minister of Foreign Affairs for Northern Ireland, Brandon Lewis, told the British Parliament that the government`s internal market bill would „violate international law“.“  The bill gives the government new powers in several areas, including Northern Ireland, to amend Brexit laws through secondary laws, instead of in the first place, which has the potential to reduce parliamentary oversight. After being passed at second reading on Friday afternoon by 124 votes, the bill moves on to the next phase after the Christmas break. After the WAB becomes law, the withdrawal agreement must also be ratified by the European Parliament. 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.  On 15 November 2018, the day after the agreement and support from the British Government Cabinet were presented, several members of the
