Gyles Brandreth's Marriage Act 1994 and wedding rules
17 June 2011 Last updated at 12:55 BST
Former Conservative MP Gyles Brandreth recalled how a letter from a constituent spurred him on to bring in a law relaxing rules on where people could marry.
The TV presenter explained his successful bid to bring in the Marriage Act 1994, which meant people no longer had to marry in church, and could hold services where they liked.
He also revealed why people used to send him wedding cake, and he made a fresh appeal for more.
