LONDON (AP) - Boris Johnson, a prominent campaigner for British withdrawal from the European Union, says he will not be a candidate for leadership of Conservative Party.

Johnson's decision means Justice Secretary Michael Gove and Home Secretary Theresa May are front-runners in the race.

They and others will compete to succeed Prime Minister David Cameron.
