LONDON (AP) — The British prime minister's office says Theresa May will try again next month to secure Parliament's backing for a deal to leave the European Union.

Downing Street said Tuesday that May intends to ask lawmakers to vote on a withdrawal agreement bill starting the week of June 3.

Parliament has three times rejected the divorce deal May and the EU struck late last year.

But the prime minister's spokesman, James Slack, says it is "imperative" for the deal to win lawmakers' approval before Parliament starts its summer break in late July.

It is far from clear how the government plans to persuade a majority of lawmakers to back May's EU divorce deal.

Her government is in talks with the opposition Labour Party on a compromise, but so far without signs of much progress.
