A politician has cut ties with a Christian charity that is against gay marriage, which sponsored an intern in his office, adding to pressure on an Enfield MP to do the same.

Tottenham MP David Lammy said he would not continue to work with Christian organisation CARE – who paid an intern £5,500 to work in his office for a year from January last year – after an Enfield Independent investigation.

His decision to abandon CARE piles pressure on Enfield Southgate MP David Burrowes, who helped launched the Coalition for Marriage group on Monday, and said he would continue to accept an intern from the charity.

Mr Burrowes has been criticised by more than 250 people who have signed up to a Facebook group calling on him to listen to their views, as well as the Enfield Lesbian, Gay, Bisexual and Transgender Network.

He said on Monday: “My views are that the values of marriage should be between a man and a woman, and is something that is set out in statute hundreds of times – if you change the shape of marriage, then you change its purpose and risk changing the meaning of it.”

CARE also pays £5,500 in sponsorship for an intern to work in Mr Burrowes' office every other year, but both he and the organisation deny it is a lobby group or has had any influence on policy at any time.

The group opposes gay marriage legislation set to be introduced into Parliament later this year, and sponsored a London event in 2009, which discussed “therapeutic approaches to and understandings of same sex attraction” and “mentoring the sexually broken”.

Mr Lammy told the Enfield Independent: “My record on gay rights stands for itself and I’ll be voting in favour of the gay marriage bill.

“I’ve worked with CARE in the past on betting shops – which is an issue that still blights Tottenham – and I accepted an intern to help in my office, which is the busiest in the country.

“But I had no idea they held these views and my position now is that I won’t be taking another intern because I can’t agree with their extreme views.”

The Tottenham MP, who is a Christian, has voted strongly for furthering gay rights since being elected in 2000. Gay rights charity Stonewall gave him a 93 per cent score in a study of pro-equal rights MPs at the last General Election.

The charity has provided the interns to 18 MPs as part of its Leadership Programme, which it says places people with influential Christians in public life to gain experience.

A public consultation on how to make civil marriage available to same-sex couples will be launched next month, while Prime Minister David Cameron told last October's Conservative Party conference he supported gay marriage.
