BRUSSELS (Reuters) - The European Union will grant Britain an extension to its Brexit negotiating period, but the length of the delay will depend on whether Prime Minister Theresa May is able to win a vote in parliament on an exit agreement next week, draft summit conclusions said.

The updated conclusions for an EU leaders’ summit, which have yet to be finalised, said the bloc would grant an extension to May 22 if May is able to get the existing Brexit divorce deal approved by the British parliament.

If she is unable to do so, Britain would only be give a Brexit delay until April 12. At this point the country would face a disorderly Brexit, or could ask for another extension if it agreed to hold European Parliament elections on its soil on May 23-26.

“The European Council agrees to an extension until 22 May 2019, provided the Withdrawal Agreement is approved by the House of Commons next week,” said the updated draft of the EU leaders’ agreement on Brexit, which was seen by Reuters.

“If the Withdrawal Agreement is not approved by the House of Commons next week, the European Council agrees to an extension until 12 April 2019 and expects the United Kingdom to indicate a way forward at the latest by this date.”
