Sadiq Khan has released a video to mark the 10th anniversary of the July bombings in London.
Khan, along with Boris Johnson, Tessa Jowell, Zac Goldsmith, Syed Kamall, David Lammy and Caroline Pidgeon, will take part in “Walk Together”, an intiative by the think-tank British Future. Londoners are being urged to get off the bus or the tube a stop early and walk the rest of the way to pay tribute to the victims of the attacks.
