In an obliterating assault on every aspect of Mr Khan’s tenure, the Tory candidate for the London Mayoral election next year told Express.co.uk the mayor has failed to deliver what he pledged in his manifesto. He explained: “I think there are a lot of problems that London has faced that Sadiq has to answer for. He’s campaigned the whole time and delivered very little.
