British Prime Minister Theresa May will meet German Chancellor Angela Merkel and French President Emmanuel Macron on Tuesday to argue for a Brexit delay.

Britain’s departure from the EU has already been delayed once but May is asking for yet more time as she courts veteran socialist Jeremy Corbyn, whose opposition Labour Party wants to keep Britain more closely tied to the bloc after Brexit.

While May travels to Berlin and Paris ahead of an emergency EU summit in Brussels on Wednesday, British lawmakers will hold a 90-minute debate on her proposal to delay Britain’s EU departure date to June 30 from April 12.
