Article 50 to be triggered on 29 March / President Tusk calls a European Council on Brexit for 29 April

The United Kingdom Government announced its intention on the 20 March 2017, in a letter to European Council President Donald Tusk, to invoke Article 50 of the Lisbon Treaty on 29 March 2017 - the formal process for the start of the negotiations for the United Kingdom to leave the European Union.

On the 21 March 2017 President Tusk announced that he would call a European Council, in an EU27 format (without the UK), on 29 April 2017 to adopt the guidelines for the Brexit talks.
