Nick Clegg has confirmed that he opposes the introduction of a tax break for married couples.
David Cameron promised a transferrable tax allowance worth £150 a year, where one spouse stays at home, in the Conservative Party manifesto.
But the Liberal Democrats are against the move.
Nick Clegg said the tax break was unfair on people who choose not to marry.
He said: “You don’t need the taxman to tell you whether you should get married or not.”
The Daily Mail editorial today criticised Nick Clegg’s opposition to the tax break, saying that even a “modest sum would send a powerful message that this government is on the side of couples who make a lifelong commitment to each other.”
MPs and critics were outraged no mention of the allowance was made in Chancellor George Osborne’s Autumn Statement.
Christian Guy, the Managing Director of think-tank the Centre for Social Justice said it was “disappointing” the pledge is yet to be fulfilled, as it would have a “positive impact on the incomes of the poorest working households”.
And former Children’s Minister Tim Loughton MP had said the Autumn Statement was the “last opportunity” for the Government to show their support for marriage.
David Cameron has said he is “absolutely committed” to introducing the measure.
