Donald Tusk is also set to publish draft guidelines for states
European Council President Donald Tusk has announced an EU Council summit meeting on April 29th to discuss Brexit.
Brexit guidelines for the other EU 27 member states will be adopted at the meeting.
Tweeting, Mr Tusk said: "Priority must be certainty, clarity for all: citizens, companies & member states."
I will call #EUCO on 29/4 to adopt EU27 Brexit Guidelines. Priority must be certainty, clarity for all: citizens, companies & member states.— Donald Tusk (@eucopresident) March 21, 2017
Mr Tusk has also announced plans to present draft guidelines to the other member states within 48 hours of Brexit being triggered.
The UK said Monday it will trigger Article 50 on March 29th, starting the two-year process of leaving the EU.
A statement from the UK's Department for Exiting the European Union said:"This meets the UK’s longstanding commitment to trigger Article 50 by the end of March 2017."
While Brexit Secretary, David Davis, added: "Last June, the people of the UK made the historic decision to leave the EU. Next Wednesday, the Government will deliver on that decision and formally start the process by triggering Article 50.
"We are on the threshold of the most important negotiation for this country for a generation.
"The government is clear in its aims: a deal that works for every nation and region of the UK and indeed for all of Europe – a new, positive partnership between the UK and our friends and allies in the European Union."
The UK and EU have two years from the date of the trigger, March 29th, to reach agreement.
Failing that, Britain could either leave without agreement - or the two year period can be extended.
However this can only be done if the the European Council, in agreement with Britain, unanimously decides to do so.
