Brexit and citizens – Withdrawal with a deal
The draft withdrawal agreement also covers the necessary provisions on the transitional arrangements. The withdrawal agreement is expected to enter into force on 30 March 2019. This will mark the start of a transition period lasting until 31 December 2020. During the transition period, the UK will comply with the EU legislation and existing international agreements. It will remain part of the single market and the Customs Union but will no longer be involved in the EU's decision-making procedures.
