Both the draft withdrawal agreement and the political declaration have a potentially considerable impact on the British Constitution. Some of the constitutional issues that are likely to arise in each bill on the implementation of the withdrawal agreement are: the British Parliament must proceed with two approval procedures before the United Kingdom can ratify the withdrawal agreement. Both the EU Law (Withdrawal Act 2018) and the Constitutional Reform Act 2010 and the Governance Act (CRAG) are obstacles to the UK`s ability to ratify the negotiated agreement. The Withdrawal Act also provides for parliamentary procedure in the event of a rejection of an agreement by the House of Commons or if a negotiated agreement is ever reached. The Gibraltar Protocol will apply until the end of the transitional period, with the exception of the citizens` rights provisions, which will also be maintained. The protocol provides for the preparation of the application of the citizens` rights part of the VA, which allows the application of EU law at Gibraltar airport if the United Kingdom and Spain agree on this point; underpins cooperation between Spain and the United Kingdom in tax matters, environmental protection and fisheries, as well as in policing and customs matters. The agreements between the United Kingdom and Spain facilitate cooperation between the competent authorities of Gibraltar and Spain at the operational level, including the use of joint committees on citizens` rights, the environment, the police and customs and tobacco. EU and UK negotiators have reached an agreement on the draft withdrawal agreement that will allow the European Council (Article 50) to adopt guidance on the framework for future EU-UK relations on 23 March 2018. It added that any deviation from the withdrawal agreement, however weak, would “violate international law and undermine trust.” The agreement covers issues such as money, citizens` rights, border agreements and dispute resolution.

It also includes a transition period and an overview of the future relationship between the UK and the EU. It was published on 14 November 2018 and was the result of the Brexit negotiations. The agreement was approved by the heads of state and government of the other 27 EU countries[9] and by the British government led by Prime Minister Theresa May, but it faced opposition from the British Parliament, which needed approval for ratification. The approval of the European Parliament would also have been necessary. On January 15, 2019, the House of Commons rejected the withdrawal agreement by 432 votes to 202. [10] The House of Commons again rejected the agreement by 391 votes to 242 on 12 March 2019 and rejected it a third time, on 29 March 2019, by 344 votes to 286. On 22 October 2019, the revised withdrawal agreement negotiated by Boris Johnson`s government approved the first phase in Parliament, but Johnson halted the legislative process when the accelerated approval programme failed to receive the necessary support and announced his intention to declare a general election. [12] On 23 January 2020, Parliament ratified the agreement by adopting the withdrawal agreement; On 29 January 2020, the European Parliament approved the withdrawal agreement.

It was then concluded by the Council of the European Union on 30 January 2020. Some EU rules on food and agriculture also apply to NI during the backstop period. Existing controls on animals and animal products moving from the UK to NI need to be strengthened. The political statement states that provisions to address health and plant protection barriers to trade barriers should be introduced “on the basis of WTO agreements and going beyond.”
