Our complicated tax system makes it harder for people to start a family and often discriminates against married couples.
Introducing an allowance that lets families share some of their personal allowance would help tackle poverty and reduce the perverse disincentives created by our dysfunctional tax code.
The Government could go much further and reform our tax system to help everybody who is struggling with the cost of living, not just married couples.
Landmark plans to legalise gay marriage got the green light in the Commons, despite a majority of Tories failing to support the Government.
The Prime Minister will read the letter delivered to Number 10, take their views on board, but not change his mind over gay marriage.
Many Conservative MPs just do not understand the move when the tax measure is in the Coalition Agreement.
