The Marriage Foundation, launched by High Court Judge, Sir Paul Coleridge, is calling on ministers to tackle family breakdown by encouraging cohabiting couples to get married.
The recommendation comes in the first published evidence to the Family Stability Review launched by the Work and Pensions Secretary, Iain Duncan Smith.
The Foundation’s report reveals that families most at risk are those with unmarried new parents. It also finds that couples living together make up less than one in five parents, but half of all family breakdowns.
