Having quit the Conservative Party, Rory Stewart has announced he is running as an independent candidate to be the next London Mayor. He agreed that if he wins "it will of course damage the Labour Party, the Conservative Party and the Lib Dems", but he believes "these parties are going too much to the extremes". The former Tory MP also said he would like his tombstone to say 'Mayor of London'. Report by Czubalam.
