Brexit is the label for the process of terminating the membership of the United Kingdom of Great Britain and Northern Ireland in the European Union. It was launched by a referendum on the UKʼs EU membership in June 2016 and then it was initiated formally by the activation of Article 50 of the EU Treaty on 29 March 2017. The Brexit negotiations included talks on the conditions for terminating the EU membership as well as the future relationship between the UK and the EU. Although the United Kingdom has formally ceased to be a member of the EU at the beginning of February 2020, the negotiations on their future relations are still ongoing thanks to the introduction of a transitional period.
