Jack Straw, a former cabinet minister in the UK government, has joined other senior politcians and celebrities to make a video for a campaign promoting same-sex marriage.

Out4Marriage is getting political figures, famous names and ordinary members of the public to record a YouTube clip explaining why they support marriage equality.

The Blackburn MP, who was Home, Justice and Foreign Secretary during the last Labour government, has now made his own video.

In her Out4Marriage video released today Straw said: 'I'm of the generation which saw the harm, the real harm, that was done to gay people, gay men, when they couldn't show their affection and love for their partners in the way that straight people can.

'It was terrible and because I saw how terrible it was, it's been one of my commitments to ensure that there are real equal rights for everybody, regardless of their sexuality.

'For the life of me, I don't understand those who say that hetereosexual couples are most stable if they are in marriage and yet deny that route to gay couples.'

Yesterday (24 May), Home Secretary Theresa May became the most senior minister to back Out4Marriage.

May is responsible for equality and the government’s consultation on how to introduce same-sex civil marriages is headed by the Home Office.

Celebrities to also back the campaign include Britain’s Got Talent judge David Walliams, girl group The Saturdays and gay author, actor, TV presenter and comic Stephen Fry who have both sent supportive tweets.

The Out4Marriage campaign is headed up by the Coalition for Equal Marriage, Remarkable and Pink News and is being supported by a range of LGBT media, including Gay Star News.

The UK government wants to legalize same-sex marriage in England and Wales and there is just a month to go to respond to their consultation on it. Similar moves are also happening in Scotland.

You can find Out4Marriage on Facebook, Twitter and YouTube.
