LONDON, May 3 (Xinhua) -- British Conservative candidate Boris Johnson was elected mayor of London, ending Ken Livingstone's eight-year reign at City Hall, local media reported on Saturday.

    The result put further pressure on Prime Minister Gordon Brown after his party suffered its worst council election results in four decades, according to Sky TV early Saturday.

    Johnson said, "I will work flat out from now on to earn your trust and to dispel some of the myths that have been created about me."

    Livingstone accepted defeat in the contest and said it was his own fault that he did not win a third election.

    "You can't be mayor for eight years and then if you don't win that third term, say it was somebody else's fault," he said.

    Conservative leader David Cameron and New York mayor Michael Bloomberg were among the first to congratulate Johnson.
