Brexit key dates: When is the UK leaving the EU?

All the main events ahead of the big day on 29 March 2019

As Britain prepares to leave the EU on 29 March 2019, much uncertainty hangs in the air.

Will that fixed date be extended to allow for further negotiations? What kind of deal will we leave with and what scenarios will we face if we don't strike a deal?

And will there be a second referendum, to give the people a Final Say?

This will all become clearer in the months ahead, across a number of crucial votes, summits and negotiations.

We'll be keeping track of all the key dates to keep an eye out for, as one of the biggest political changes in British history approaches.

18-19 October 2018: EU summit

This gathering of the 28 EU member states will be held in Austria, and it is the point at which all sides hope to agree the terms of the UK's withdrawal agreement. This will include the key issues of the Irish border and any potential trade deal between the two sides after Brexit.
