framework agreements concluded after the end of the transitional period in accordance with a procedure referred to in point (a) of this paragraph. The obligations arising from the Cooperation Agreement between the European Community and its Member States, of the one part, and the Swiss Confederation, of the other part, to combat fraud and other illegal activities affecting their financial interests (11) 2. Point (a) of paragraph 1 and point (a) of Article 67(2) of this Agreement shall also apply to the provisions of Regulation (EU) No 1215/2012 established under the Agreement between the European Communities, the Community and the Kingdom of Denmark, on jurisdiction and the recognition and enforcement of judgments in civil and commercial matters (88). If the UK had left the EU without a deal, UK nationals would have gone overnight from EU citizens enjoying rights of entry, residence rights, market freedoms and free movement rights to third-country immigrants who need a residence and work permit and, in the worst case, an entry visa. The Commission`s Brexit preparedness planning has therefore encouraged Member States to formulate their contingency plans to deal with this loss of EU citizenship by British nationals before the first Brexit deadline, on 29 March 2019. As regards the residence rights of UK citizens and their family members, the Agreement allows EU Member States to choose between two systems: the system of constituent residence referred to in Article 18(1) and the system of declaratory residence referred to in Article 18(4) of the Agreement. Yet despite attempts by British nationals to find a way to retain EU citizenship, Brexit negotiations between the EU and the UK have made it clear that there is no panacea for losing EU citizenship after Brexit. Article 50(3) TEU is the mechanism by which citizenship of the Union is withdrawn. It provides that the Treaties no longer apply to the State which has notified its withdrawal from the European Union in accordance with Article 50 TEU. Thus, when the Withdrawal Agreement enters into force, the United Kingdom ceases to be a Member State and persons of British nationality no longer fulfil the privacy condition laid down in Article 20 TFEU of citizenship of the Union – `nationality of a Member State`. In this way, the persons referred to in art.

20 para. 2 TFEU, the rights of citizenship of the Union previously enjoyed by British nationals are simply abolished. Other important rights of individuals in the EU Treaties that depend on the nationality of a Member State, such as the right to work and settle in another Member State and the right to provide cross-border services, are also lost by the effect of Article 50 TEU. .
