Kulveer Ranger, Boris Johnson's director of transport policy, said that a design competition would be launched - but if no bid was good enough they would look again at the pledge.
He added that although Mr Johnson is very keen to bring in a new-style bus in place of bendy buses, they would not press ahead with the idea for the sake of it.
Mr Johnson made phasing out bendy buses a priority, initially saying new Routemasters would cost £8million to run with conductors. However, he later admitted the figure would be nearer £100million.The magic Routemasters, it seems, were what Johnson's strategist, Lynton Crosby, would call a "non-core promise". It is not clear exactly how many Londoners voted for Johnson primarily because they wanted to see the return of those friendly red buses. As John Lydon once said, "ever get the feeling you've been cheated?"
Petrolheads and Chelsea tractor drivers can rejoice, though, as the congestion charge looks set to be "reviewed" (i.e., cut back); the western extension looks set to be scrapped altogether. Jeremy Clarkson, however, will be disappointed that a £500/day congestion charge on bicycles is not on the agenda.
