Turning to Culture Secretary Maria Miller shortly before the vote, shadow minister for women and equalities Yvette Cooper said:
"We can only wonder what would happen if you and I leapt up and started leading a Eurovision-style chorus perhaps of congratulations perhaps Abba-style, maybe not 'One Man, One Woman' but certainly 'I Do, I Do, I Do'.
"I have heard Conservative members talk about the anger in their constituencies. And I hope they will now be able to stop talking about the anger and start talking about the joy. Because this is about the joy that we can deliver to those that want to get married just as their parents did.
"Let's be loud and proud, let's start the singing. Let's celebrate, not discriminate. Let's put aside the anger and hear it for the joy."
In an article for ITV News, Conservative councillor Mary Douglas talks gay marriage and urges David Cameron to return to 'core values'.
David Cameron has defended the equal marriage bill while Nick Clegg claims a civil partnership amendment is laced with an "ulterior motive".
