A new three-minute campaign video has been released by the Coalition for Marriage, the group leading the opposition to plans to redefine marriage.
It says marriage between one man and one woman is important for raising children, and marriage doesn’t take any rights away from anyone.
Over 80 per cent of people think children do best when raised by their own mother and father in a committed relationship, the video adds.
And it points out that 76 per cent of children in Britain are today raised by two parents in 5.6 million families.
The Coalition for Marriage has attracted the support of over 600,000 people in the UK who have signed its petition.
The petition supports the current definition of marriage and calls on the Government to leave it alone.
Prime Minister David Cameron has come under intense pressure from within his own party to ditch his plans to redefine marriage.
A recent poll showed that over 70 per cent of Conservative Party chairmen think the proposals should be dropped and nearly half of associations have lost members over the issue.
Six in ten chairmen say the proposal will cost the party votes, and 71 per cent say policy had damaged the PM’s standing with the party.
