Tory leadership: Boris Johnson and Jeremy Hunt are final two
Jeremy Hunt has promised Boris Johnson "the fight of his life" as the two compete to become the next Conservative leader and PM.
Mr Johnson said he was "honoured" to get the backing of 160 MPs in the final ballot of the party's MPs - more than half of the total.
Mr Hunt got 77 votes - two more votes than the next candidate Michael Gove.
Mr Johnson and Mr Hunt now face a vote involving up to 160,000 Tory members, with a result due by late July.
All 313 Conservative MPs took part in the final ballot in the House of Commons, with one paper spoilt.
Mr Johnson's victory in the latest round of the contest had been widely expected, but Environment Secretary Mr Gove and Foreign Secretary Mr Hunt had been engaged for several days in a fight for second place.
In the penultimate MPs' ballot, earlier on Thursday, Mr Gove overtook his rival, only to see his lead reversed in the final vote.
