Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union and the European Atomic Energy Community. L 29 31.01.19, pp. 7-187 The most important provisions of the Withdrawal Agreement include: According to the WAB Law, the Withdrawal Agreement must also be ratified by the European Parliament. The Withdrawal Agreement provides for a transition period until 31 December 2020, during which the UK will remain in the Single Market to ensure smooth trade until a long-term relationship is agreed. If no agreement is reached by that date, the UK will leave the single market on 1 January 2021 without a trade agreement. A non-binding political declaration on the future relationship between the EU and the UK is closely linked to the Withdrawal Agreement. On the same day, the European Council (Article 50) approved these texts. According to Sam Lowe, a fellow at the Centre for European Reform, the amendment excludes labour standards from dispute settlement mechanisms.  In addition, the mechanism for a level playing field has been moved from the legally binding Withdrawal Agreement to the Political Declaration and the line in the Political Declaration that „the UK will consider aligning itself with EU legislation in relevant areas“ has been deleted.  The WAB converts Boris Johnson`s withdrawal agreement, which is a draft international treaty, into British law and gives the government permission to ratify it. . .
