Mayor Ken Livingstone, transport commissioner Bob Kiley and LU share the view that the claimed lack of improvement in the Tube justifies their hard fought opposition to the public-private partnership (PPP). Mr O'Toole said of the private sector: "They may give us a substantially new Tube line for the Olympics but are not doing anything to help people get to work next week or even next month. These guys are supposed to be the cavalry but so far, they're the same world-weary infantry we saw under LU."
