London mayoral election: Zac Goldsmith 'won't be like Boris Johnson'

The Conservative Party has unveiled Zac Goldsmith as its candidate for the London mayoral election in 2016.

The London MP and environmentalist is up against the Labour MP Sadiq Khan, among others.

If he wins he will follow on from Tory Boris Johnson, who stands down next year after two terms in office.

But Mr Goldsmith told the BBC's Robin Brant he will be a different type of mayor.
