Britain’s leading campaign group supporting traditional marriage

The Coalition for Marriage is Britain’s leading campaign group supporting traditional marriage which is between a man and a woman, to the exclusion of all others and for life.


People signed the C4M national petition against the redefinition of marriage.

Together we act with our hundreds of thousands of supporters to protect the right to publicly support traditional marriage and to assert its rightful place as the ‘gold standard’ in our society.
