Tax breaks for married couples will be introduced within the next two years, David Cameron pledged today following Conservatives accusations that he is failing to support family life.
The Prime Minister has come under fire from party traditionalists for scrapping child benefit for wealthier families and pressing ahead with plans to introduce same-sex marriages.
However, he promised he would unveil proposals to introduce transferable tax allowances for married couples to come into force by the time of the next election in May 2015.
The plans were contained in the Coalition Agreement, along with the stipulation that the Liberal Democrats would be allowed to abstain in the vote putting them into place.
Mr Cameron made his commitment during campaigning in Carlisle ahead of next week's local elections.
Asked whether he still supported the proposals, he said: "Yes I do, we set them out at the last election in the Conservative manifesto.
"The Coalition Agreement specifically said that while the Liberal Democrats don't agree with them they would abstain if we promoted them. That's exactly what we will do before the end of this Parliament."
Mr Cameron has reportedly been considering introducing the measures this autumn. But asked about his planned timetable, he replied: "It will be before the end of this Parliament."
