The EU and the UK reach an interim agreement. It includes a transition period until 31 December 2020, during which all EU rules will continue to apply. It also covers the border between Ireland and Northern Ireland. On 23 March 2018, EU and UK negotiators reached an agreement on the draft withdrawal agreement allowing the European Council (Article 50) to adopt guidelines for the framework for future eu-UK relations. 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 transition period is not extended. The United Kingdom has stated that it does not want an extension. The option of an extension was included in the withdrawal agreement. The UK and the EU have had until 1 July 2020 to agree on a possible extension. The most important elements of the draft agreement are:  On 15 November 2018, the day after the agreement was presented and the support of the British government, several members of the government, including Dominic Raab, Secretary of State for leaving the European Union, resigned.

The third area concerns the activities of the common customs territory. The fourth area concerns „good governance in the areas of taxation, environmental protection, social and labour standards, state aid, competition and state-owned enterprises. The five to eighteen provisions relate to the relevant provisions of EU law. In the ninth and tenth versions of the procedures that arise from the main sections of the project. The UK will be able to enter into trade agreements with third countries; However, the customs union would significantly reduce the UK`s ability to have very different trade relations with them, particularly with regard to products. There would be more opportunities for the UK to offer different conditions for trade in services and sectors such as public procurement. The United Kingdom and the European Union reached an agreement at the European Council on the withdrawal of the United Kingdom from Great Britain and Northern Ireland from the European Union. The revised withdrawal agreement and the political declaration were discussed and approved at the European Council on 17 October 2019.
The withdrawal agreement provides for a transitional period until 31 December 2020, during which time the UK will remain in the internal market, to ensure the smooth flow of trade until a long-term relationship is concluded.
