Justice Secretary Michael Gove plans to spell out his plans for Britain's post-European Union future as he intensifies his bid for the Conservative Party leadership.

Gove's surprise entry into the leadership race led ex-London mayor Boris Johnson to drop out. He plans a speech Friday.

Gove is contending with Home Secretary Theresa May and three others to succeed David Cameron as party leader — and prime minister.

Gove and Johnson were leaders of the campaign to persuade Britons to leave the EU bloc. Gove had been expected to back Johnson for the top job.

Some Cabinet figures are backing May. Conservative lawmakers will whittle the field down to two before the final decision is made by party members.

The winner will be announced Sept. 9.
