Ken Livingstone’s vision of redeveloping London is unworkable, planning and property consultant GVA Grimley said this week.
The firm said the private sector would have to stump up cash for the 14-year plan, which it is estimated will cost £100bn.

Stephen Brown, GVA Grimley’s head of planning, said it was doubtful that the government would back the plan with investment. He said: “There is no indication that the government can keep pace with the plans. The shortfall will need to be made up by the private sector.”

Brown added: “The growth for jobs, office floorspace and homes will not be delivered where local authorities are unable to resource and process applications fast enough.”
