Hugh Grant, star of Four Weddings and a Funeral, Love Actually, About a Boy and the Bridget Jones films, has recorded a video in support of the Out4Marriage campaign to make same-sex marriage legal in the UK.

Grant follows fellow campaigners Sir Richard Branson, The Saturdays and Paloma Faith, saying that although he was “not a massive believer in marriage”, he thought “everyone should have the same rights. If you want to get married, whether you’re gay, straight, transgender [or] whatever, you should definitely be allowed to do that.”

In his short Out4Marriage video, Grant said: “Hello I’m Hugh Grant. I’m not a massive believer in marriage; I think my own biography is testament to that but I do think that love is the same for everyone. And I do think that everyone should have the same rights. If you want to get married, whether you’re gay, straight, transgender [or] whatever, you should definitely be allowed to do that”.

Welcoming the video, Joseph Musgrave, for the Out4Marriage campaign, said: “There has been a tendency amongst some media commentators to subject the equal marriage debate to a mere political calculation.

“Although it’s great to have such a well known celebrity support us, Hugh’s key contribution is to emphasise the human element – this is all about the recognition of love and freeing people to decide how they, and not the state, choose to act on that.”

The Out4Marriage campaign is one of the most prominent groups campaigning for equal religious and civil marriage.

It has attracted support from a wide spectrum of public and private figures including Virgin founder Sir Richard Branson, the Deputy Prime Minister Nick Clegg, the Home Secretary Theresa May, Labour power couple Yvette Cooper and Ed Balls, the Bishop of Buckingham Alan Wilson, The Saturdays and singer Paloma Faith.

The campaign will release an Out4Marriage video by a major British star each week until the end of October.
