LONDON — British Prime Minister Theresa May is requesting that the deadline for her country to leave the European Union be extended until June 30.

In a letter to European Council President Donald Tusk Friday, May said that “the United Kingdom proposes that this period should end on 30 June, 2019.”

EU leaders agreed late last month to prolong the Brexit date from March 29 until April 12, unless May could push their mutually agreed divorce deal through Parliament.

The Europeans would prefer that Britain don’t take part in the May 23-26 EU elections if it is going to leave. April 12 is the last day for Britain to signal whether it will field candidates.
