This timeline provides an overview of key Brexit events, particularly as they concern Northern Ireland's position in the process.

It starts with the build-up to the EU referendum in 2016 and charts developments through the negotiation of the UK's withdrawal from the EU on 31 January 2020, the subsequent 11-month transition period and, from 1 January 2021, the full entry into force of the Protocol on Ireland/Northern Ireland. As such, it complements the Key Texts section of the website by providing links to a range of relevant legal texts, policy papers, official statements and political speeches. 

This page will be regularly updated to include latest developments in the implementation of the Withdrawal Agreement, the Protocol, and the UK's post-Brexit relationship with the EU.
