The declaration on the future relationship between the European Union and the United Kingdom, also known as the Political Declaration, is a non-binding declaration, negotiated and signed at the same time as the mandatory and broader withdrawal agreement on the uk`s withdrawal from the European Union (EU), known as Brexit, and the planned end of the transition period. The 2019 revisions also adapted elements of the political declaration and 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.  The British Parliament approved the draft agreement by adopting 2020 implementing laws (The European Union Withdrawal Agreement (Withdrawal Agreement) 2020 Act. Following the signing of the agreement, the UK Government adopted and tabled the UK`s ratification instrument on 29 January 2020.  The agreement was ratified by the Council of the European Union on 30 January 2020, after approval by the European Parliament on 29 January 2020. The UK`s withdrawal from the EU came into force on 31 January 2020 at 11 .m GMT, when the withdrawal agreement came into force in accordance with Article 185. On the European Union side, the European Parliament also approved the ratification of the agreement on 29 January 2020 and the Council of the European Union approved the conclusion of the agreement by e-mail on 30 January 2020.  That is why, on 30 January 2020, the European Union also tabled its instrument for ratification of the agreement, concluding the agreement and allowing it to enter into force on the date of the UK`s withdrawal from the EU on 31 January 2020, at 11 .m GMT.
The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments fit about 5% of the text.  The Northern Ireland Protocol, known as the Irish Backstop, was an annex to the November 2018 draft agreement outlining provisions to avoid a hard border in Ireland after the UK`s withdrawal from the European Union. The protocol provided for a provision of the safety net to deal with the circumstances in which satisfactory alternative arrangements were to come into force at the end of the transition period. This project has been replaced by a new protocol that will be described as follows. After the WAB becomes law, the withdrawal agreement must also be ratified by the European Parliament. The withdrawal agreement also contains provisions for the United Kingdom to leave the Convention setting the status of European schools, with the United Kingdom bound by the Convention and accompanying regulations on accredited European schools until the end of the last academic year of the transition period, i.e. at the end of the spring semester 2020-2021.  In the withdrawal agreement with the EU, Northern Ireland is still in the UK, but must comply with elements of the EU customs code.
