Attack adverts have accused Sadiq Khan of 'ruining' London as the race for City Hall heats up ahead of the capital's mayoral election on May 6. Adverts published by the Fair Tax Campaign group also claim the Labour Mayor is 'constantly blaming everyone else' for the capital's problems. The adverts published by the group, which is reportedly run by former adviser to Boris Johnson, Alex Crowley, have sparked a Labour backlash. It came as Tory candidate Shaun Bailey campaigned alongside Mr Johnson this morning at Romford Market as he returned to his claim that Mr Khan had 'bankrupted' Transport for London, an accusation Mr Khan has denied.
