MPs have backed David Cameron's plan to legalise gay marriage by 400 votes to 175, a majority of 225.
Cleethorpes Conservative MP Martin Vickers opposed it, while Grimsby MP Austin Mitchell - who earlier today said he intended to abstain - voted yes after listening to the Commons debate.
Mr Vickers said same-sex marriage would "potentially alienate thousands" of Conservative supporters.
Mr Mitchell said: " I was very moved by some of the speeches."
