Mr Johnson said: “I’m delighted to confirm Mike Brown as London’s new Transport Commissioner. Under Mike’s leadership, we’ve seen record numbers of customers carried on our Tube, DLR and London Overground networks and Tube delays have fallen by well over 40 per cent since 2010. “He brings decades of service, experience and leadership to the role and is the right person to lead the next wave of modernisation and improvement at TfL, to ensure London continues to grow and prosper to the benefit of the whole country.”
