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 2019 revisions also adapted elements of the political statement that replaced the word “appropriate” with “appropriate” with respect to labour standards. According to Sam Lowe, a trade fellow at the Centre for European Reform, the amendment excludes labour standards from dispute resolution mechanisms.  In addition, the Equal Competition Mechanism has been postponed from the legally binding withdrawal agreement to the political declaration, and the line of the political statement that “the United Kingdom will consider taking into account alignment with trade union rules in the relevant areas” has been removed.  publications.parliament.uk/pa/bills/cbill/58-01/0001/20001.pdf On November 13, 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.  A number of clauses in the previous version of the act have been removed. These include the Brexit withdrawal agreement, officially titled the agreement to withdraw the United Kingdom from Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community, a treaty signed on 24 January 2020 between the European Union (EU), Euratom and the United Kingdom (Uk), which sets the conditions for the UK`s withdrawal from the EU and Euratom. The text of the treaty was published on 17 October 2019 and is a renegotiated version of an agreement published six months earlier. The previous version of the withdrawal agreement was rejected three times by the House of Commons, leading Queen Elizabeth II to accept Theresa May`s resignation as Prime Minister of the United Kingdom and appoint Boris Johnson as the new Prime Minister on 24 July 2019.
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”.”  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 prevents British governments from forcing the House of Commons to vote several times on a subject already voted on by the House of Commons
