The Prime Minister has held a party for gay activists in Downing Street and said he wants to export same-sex marriage all over the world.
But he has been criticised for further alienating traditionalists and driving them into the arms of other parties like UKIP.
The Number 10 drinks reception was organised to celebrate the passage of the same-sex marriage Bill.
Mr Cameron gave a speech boasting about the speed with which he rushed the legislation through Parliament.
And he said he would send the team of civil servants who worked on the Bill across the globe to show how it is done.
Mr Cameron also said passing the same-sex marriage Bill was just the start, and that he wanted to see gay rights issues pressed in schools.
But Richard Littlejohn, writing in the Daily Mail today, criticised the Prime Minister for pandering to the gay lobby.
Littlejohn said: “What does he hope to achieve by embarking on a mission to proselytise same-sex marriage around the world, other than to bask in the admiration of the gay lobby?
“It will only serve to reopen old wounds and alienate still further many of his own supporters, already heading to UKIP in droves.”
At the Downing Street party the Prime Minister said: “I’ve told the bill team I’m now going to reassign them because, of course, all over the world people would have been watching this piece of legislation.”
“We’ve set something, I think, of an example of how to pass good legislation in good time. Many other countries are going to want to copy this.”
“So I’m going to export the bill team. I think they can be part of this global race and take it around the world,” he added.
