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.
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.
