David Cameron has praised same-sex marriage as a “huge, historic change” in a new video released at the weekend.
He was speaking to coincide with Pride – an annual homosexual event taking place in London.
Mr Cameron said: “Since I recorded last year’s message there has been one huge, historic change in Britain: the institution of marriage is now open to all.
“Whether you’re a man and a man, a woman and a woman or a woman and a man, your love for one another is equal in the eyes of the law.”
He also said the Foreign Office was pushing for pro-gay changes in other countries, and that Britain should “encourage the rest of our world to take our lead”.
The Prime Minister also spoke of his desire to export same-sex marriage around the world at a Downing Street party last year.
His latest comments came as he was warned that declining membership of the Conservative Party since he became leader could “prove fatal” in the 2015 General Election.
Columnist Andrew Pierce, writing in the Daily Mail, said the drop in membership is perhaps “not surprising considering that Cameron has offended many traditional Conservative voters with his liberal, metropolitan agenda”.
“Particularly unpopular have been his enthusiastic introduction of gay marriage, his pandering to his Lib Dem partners, his aides smearing Ukip supporters as ‘swivel-eyed loons’, and his delusion that he can get Britain a better deal from the EU”, Pierce wrote.
He added that the drop in numbers, “could prove fatal at next year’s General Election if declining membership means there are not enough volunteers to get the party faithful to polling stations”.
