The government announced its intention to introduce the law in the Queen`s Speech on 19 December 2019. The bill is necessary for the UK to leave the European Union through an agreement on 31 January 2020. The WAB agrees to withdraw Boris Johnson, which is a draft international treaty, into British law and gives the government permission to ratify it. On July 24, 2018, the government presented a white paper on the bill and how legislation works.  The bill was first introduced by the government at the second session stagnated on 21 October 2019 by the government, entitled “A Bill to Implement, and make other provision in connection with, the agreement between the United Kingdom and the EU under Art 50, paragraph 2 of the Treaty on European Union which sets the arrangements for the rekingdom from the EU”.  This bill was not discussed further after second reading in the House of Commons on October 22, 2019, and passed on November 6, when Parliament was dissolved in preparation for the 2019 general election. After the WAB becomes law, the withdrawal agreement must also be ratified by the European Parliament. On January 22, 2020, the law was passed by the House of Lords without further amendment. The next day she obtained royal approval.   On January 21, 2020, the House of Lords passed the law after passing five amendments. However, these amendments were overturned by the House of Commons the next day.   On 13 November 2017, Brexit Minister David Davis announced a bill to enshrine the withdrawal agreement in national law through primary legislation.
In further talks in the House of Commons, Davis said that if the UK decided not to pass the law on 29 March 2019, the UK would remain on track to leave the EU without a deal, having invoked Article 50 in March 2017, following the adoption of the Notification of Withdrawal Act 2017.  In October 2019, the government introduced the EU law (withdrawal agreement). The October law would have ratified and implemented the UK`s EU withdrawal agreement. Although the October Act received a second reading, his application for the program was denied. This was partly because of concerns about the speed with which the government proposed to get the October bill through the House of Commons. The October bill failed when Parliament dissolved the parliamentary elections on 12 December 2019. Scottish Government Memorandum (326KB pdf tabled 22 October 2019) The bill was first introduced in Parliament on 21 October 2019, but expired on 6 November with the dissolution of Parliament in preparation for the December 2019 general election. The bill described by The Independent as a government “incision” on Conservative rebels would have allowed MPs to review and amend each “line-by-line” agreement.
 Conservative MP Steve Baker wrote to The Times stating that the new bill “gives any agreement that we have a good reputation with the EU in British law” and that it is compatible with the referendum result of “giving more control over how we are governed by the British Parliament.”  On 20 December 2019, MEPs approved the government`s European law (withdrawal agreement) by 358 votes to 234 (December Law).
