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.
Responding to last night's vote on gay marriage at Prime Minister's Questions, David Cameron said:
I'm a marriage man. I'm a great supporter of marriage. I want to promote marriage, to defend marriage, encourage marriage. And the great thing about last night's vote is that two gay people who love each other will now be able to get married and I think that's an important advance.
After MPs backed plan to legalise gay marriage by 400 votes to 175 on Tuesday, Virgin Holidays capitalised on the opportunity to advertise its travel offers by tweeting this picture:
Culture Secretary Maria Miller has suggested the Conservative rebellion on plans for gay marriage came as no surprise to the Government.
Tonight's Conservative rebellion on gay marriage shows the Prime Minister's political strategy to rebrand or redefine his party was "inappropriate", according to a leading Tory MP.
Ministerial aide David Burrowes, one of the leading opponents of the plans to legalise same-sex marriage, said it was "unprecedented" for more than half the party to fail to support a Government Bill.
Labour MP Chris Bryant, who has sparred frequently with David Cameron in the Commons, has welcomed a rare union with the Prime Minister on the issue of gay marriage.
I have had my differences with Mr Cameron but I'm glad we had the chance to vote on this today. Glad some Tories have moved since 2004.From @ChrisBryantMP on Twitter:
The Liberal Democrat MP Sarah Teather has blogged about why she voted against the same-sex marriage bill. She was one of only four MPs in her party to do so.
She said it was "one of the most difficult decisions" she has ever taken and that she was torn between her support for liberal gay rights and her commitment to Catholicism.

I believe that the link between family life and marriage is important. We know that permanent stable loving relationships between parents are very important for children.
Such relationships make it much easier to offer the kind of consistent loving parenting that enables children to grow into healthy happy adults able to play their part in society.
I recognise that this kind of stability can exist outside of marriage, but the act of giving and receiving vows in front of others and making a commitment for life is an aid to stability.

David Cameron has split the Conservative Party in half on gay marriage and failed to win a majority of Tory MPs. Labour win.From @SJacksonMP on Twitter:
