Mr Johnson, who is a favourite to be the next Conservative leader, said he supports more marriage in society regardless of people’s sexual orientation.
He made the remarks in a new video for the Out4Marriage campaign, as David Cameron faces a revolt from within his party over whether to bring in new laws legalising gay marriage.
Dozens of Conservative MPs are expected to vote with their consciences against the proposals, with many objecting on religious grounds.
However, Mr Johnson threw his weight behind the plans yesterday, joining Theresa May, the Home Secretary, and Nick Clegg, the Deputy Prime Minister, in recording a message for the campaign.
He said : “One of the amazing things about London is that it’s not only got a declining crime rate, declining murder rate, more theatres than New York, less rainfall than Rome but it’s also one of the few places in the country where the rate of marriage is actually increasing.
“And I see absolutely no reason why that happy state should be denied to anybody in our country.”
Mr Johnson was one of the first politicians to say he was open to allowing gay marriage, before the Prime Minister made it clear he supported the idea. » | Rowena Mason, Political Correspondent | Monday, August 20, 2012
