The United Kingdom left the European Union at midnight (Northern European time) on 31 January 2020 when the withdrawal agreement came into force. After an unprecedented vote on 4 December 2018, MEPs ruled that the UK government was not respecting Parliament because it refused to give Parliament full legal advice on the consequences of its proposed withdrawal terms. [29] The focus of the consultation was on the legal effect of the “backstop” agreement for Northern Ireland, the Republic of Ireland and the rest of the United Kingdom with regard to the CUSTOMS border between the EU and the United Kingdom and its impact on the Good Friday agreement that led to the end of the unrest in Northern Ireland, including whether , according to the proposals, the UK would be certain that it would be able to leave the EU in a practical sense. On 17 October 2019, the UK and the EU agreed on the terms of the UK`s exit from the EU (Brexit) and a transitional period until 31 December 2020. “I think a brief extension will be possible, but it will be conditional on a favourable vote on the withdrawal agreement in the House of Commons,” European Council President Donald Tusk said on 20 March. “We cannot give up looking for a positive solution until the last moment,” Tusk added. His statement followed a request by British Prime Minister Theresa May to delay Brexit until 30 June 2019. “These clauses will remain in this bill” as a safety net if the UK and the EU do not enter into a trade deal, Gove said.

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.

[45] 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). [47] 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. [48] 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”. [49] 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”.” [50] The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments amend about 5% of the text[22] The UK`s withdrawal from the EU on 31 January 2020 came into force as part of the revised divorce agreement reached by London and Brussels in October 2019.
