Brexit's fate is "in the hands of our British friends" after EU leaders agreed to delay the departure date by at least two weeks, says Donald Tusk, ONA reports citing BBC.
If MPs approve Theresa May's withdrawal deal next week - Brexit would be delayed from 29 March until 22 May.
But if they do not, the UK has until 12 April to come up with a new plan.
European Council President Mr Tusk said that until 12 April, "anything is possible" including a much longer delay or cancelling Brexit altogether.
Speaking in Brussels on Friday, he said he was "really happy" the 27 EU leaders had reached a unanimous decision to extend the two-year Article 50 process, under which the UK was due to leave the EU next Friday.
