The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments amend about 5% of the text The withdrawal agreement provides for a transitional period until 31 December 2020, during which time the UK will remain in the internal market to ensure the smooth flow of trade until a long-term relationship is concluded. If no agreement is reached by then, the UK will leave the single market without a trade deal on 1 January 2021. The withdrawal agreement is closely linked to a non-binding political declaration on future relations between the EU and the UK. The UK has launched the formal process of withdrawal negotiations by formally announcing the European Council`s intention to leave the EU. The European Parliament, including British MPs, must approve the withdrawal agreement by a simple majority, but it does not have the power to amend it. In this case, the Council of the EU must adopt it by an overqualified majority. This means that 72% of the 27 participating Member States (or 20 Member States) need help, and aid must also account for 65% of the population of the 27 Member States. Although the UK is still a full member of the EU in the COUNCIL of the EU, it is not involved in the Council`s decisions on Brexit. Despite the Westminster shocks over Brexit, now that a draft withdrawal agreement is on the table, the next step in the process of the UK`s exit from the European Union has been launched.
But what needs to be done next so that the various parts of the Brexit agreement can be ratified and what is the role of the different parliaments in this regard? 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    An abbreviated version of the withdrawal agreement, in which the annex political statement had been withdrawn, consisted of the test of “substantial amendments,” so that a third vote was held on 29 March 2019, but was rejected by 58 votes.  The EU and the United Kingdom 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.
