Conservative MP for Peterborough Stewart Jackson has taken to Twitter to criticise the Prime Minister's plans to support gay marriage but to delay a tax break for married couples:
I wonder who's advising Cameron at the moment? His political strategy - no to marriage tax breaks and yes to gay marriage - stinks.
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.
