Brexit negotiations between the United Kingdom and the European Union started on June 19, and are due to be completed by the end of March 2019. The first phase of the talks focused on the protection of rights of EU citizens in the United Kingdom and UK citizens in the bloc, as well as the UK-Irsih border and London’s financial obligations to Brussels after the withdrawal.
The second phase, to which the parties moved on earlier in December, is expected to focus on the transition period in EU-UK relations after Brexit, and their future long-term trade and security cooperation.
