PMQs: Campbell and Cameron on Christian gay cake row

9 July 2014 Last updated at 13:12 BST

Democratic Unionist Gregory Campbell asked the prime minister about possible legal action over a bakery which refused to make a cake with a message "completely at variance" with its Christian values.

He called for a "conscience clause" following the refusal of Ashers Baking Company over a message supporting gay marriage.

But David Cameron said tolerance and equality were "a very important part of being British".
