Attitudes have changed and support is growing for gay marriage, the former policing minister Nick Herbert has said.
The Conservative MP claimed allowing same-sex marriage would "fully complete the journey of equality", following the introduction of civil partnerships.
The Marriage (Same Sex Couples) Bill will be debated in Parliament on 5 February, and Mr Herbert reckoned most MPs would vote for it, with his own party "divided roughly down the middle".
