The rights of the UK and EU citizens are mutually protected for a transitional period up to 31 December 2020, by the terms and provisions of the revised UK and EU withdrawal agreement, provided the agreement has been ratified by both the UK and the EU. The UK has announced its intention to leave the EU on 31 January 2020. Although the UK officially left the EU in January, it continued to follow the rules established in Brussels during a transitional period – which will end on 31 December – while discussions on a long-term trade deal continue. The agreement also provides for a transitional period, which will last until 31 December 2020 and can be extended by mutual agreement. During the transitional period, EU legislation will continue to apply to the UK (including participation in the European Economic Area, the internal market and the customs union) and the UK will continue to contribute to the EU budget, but the UK will not be represented in EU decision-making bodies. The transition period will give businesses time to adapt to the new situation and the new era, so that the British and European governments can negotiate a new trade agreement between the EU and the UK.   The agreement was revised as part of the Johnson Department renegotiation in 2019. The amendments fit about 5% of the text.  He called on the government to withdraw the bill “by the end of the month,” adding that the withdrawal agreement contained “a number of mechanisms and remedies to remedy violations of the legal obligations contained in the text – which the European Union will not hesitate to use.” Parliament adopted the Letwin Amendment, which deprives the Prime Minister of the Brexit agreement of his support until the Adoption Agreement Bill is passed. Since the Prime Minister was unable to get a Brexit deal through Parliament before midnight on 19 October, BRITISH law asked him to send a letter to the EU requesting a three-month extension of Article 50. The Prime Minister has called for an extension that the EU has just granted. The UK must now leave the EU on 31 January (or earlier if it accepts the Prime Minister`s withdrawal agreement). On the issue of the Irish border, there is a protocol on Northern Ireland (the “backstop”) which is attached to the agreement and establishes a position of withdrawal which will only come into force in the absence of effective alternative provisions before the expiry of the transition period.
In this case, the UK will eclipse the EU`s common external tariff and Northern Ireland will stick to aspects of the internal market until such an event is carried out. Neither party can unilaterally withdraw from this customs union. The aim of this backstop agreement is to avoid a “hard” border in Ireland, where customs controls are needed.  On 15 November 2018, the day after the agreement was presented and the support of the British government cabinet, several members of the government resigned, including Dominic Raab, Secretary of State for leaving the European Union.  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 ratifying the agreement, concluding the agreement and allowing it to enter into force on the date of the UK`s withdrawal from the EU at 11 .m.
