The Tory heartlands came to Downing Street today to challenge David Cameron over legalising gay marriage. A group of senior activists handed in a letter to Number 10, warning that the upcoming vote will cause "significant damage".
As our Political Correspondent Alex Forrest reports, up to 180 Conservative MPs, including 4 Ministers, look set to defy the Prime Minister.
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.
