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.  It is essential that the transition period can be extended by a mutual agreement between the EU and the UK. Please note that, in accordance with the agreement, the transitional period can only be extended once until 31 December 2022 and that the United Kingdom and the European Union must make a decision by 1 July 2020 on whether such an extension should be made. In practice, it is unlikely that the EU will raise objections if the UK asks for an extension, so the ball will be in the british Court of Justice`s court on that front. However, to some extent, the withdrawal agreement must be supplemented by provisions of Swedish law. This concerns the rights of citizens with regard to the right of concerned British citizens and their families to continue to travel, live and work in Sweden after they leave. The more the scope of the UK-EU trade agreement is limited, the more relevant the non-agreement plans that companies have implemented at the extremes remain. Paul Hardy, DLA Piper`s Brexit director, told The Guardian on 18 December 2019: „The revised protocol places much more emphasis on giving the UK the greatest possible freedom to manage its economic relations, while maintaining as much as possible an open border on the island of Ireland. It is not so much a question of keeping trade with the EU functioning properly for the rest of the UK.
On 13 November 2018, the EU decided that „decisive progress“ had been made in the Brexit negotiations, and on 14 November the European Commission and the UK Government published a draft withdrawal agreement as well as three protocols (on the border between Ireland and Northern Ireland, the SOVEREIGN territories of the United Kingdom in Cyprus and Gibraltar) and nine annexes. The text of the negotiated withdrawal agreement and the political declaration on the framework for future EU-UK relations were approved by EU heads of state and government at a specially convened European Council on 25 November 2018. This will allow us to take the necessary steps to deal with the particular circumstances of the island of Ireland and avoid the creation of a hard border. Northern Ireland will remain in the EU`s internal goods market, but will leave the EU customs union. Essentially, the new solution means that Northern Ireland will apply all parts of the EU acquis that are needed to eliminate the need for border controls between Ireland and Northern Ireland, including with regard to customs duties and VAT. From a legal point of view, however, Northern Ireland will remain part of the CUSTOMS territory of the United Kingdom, which means that no tariffs will be applied to exports of goods from Great Britain which are proven not to leave Northern Ireland. For some defined products, no control is carried out – detailed regulation is left to the joint committee. The Northern Ireland Assembly in Stormont will have the opportunity to approve Northern Ireland, which remains in the agreement, for the first time four years after the end of the transition period and then every four years.
