Taxi drivers are warning of a shortage of black cabs in the run up to the busy Christmas period.
The firm that makes them, Manganese Bronze, has gone into administration after the recall of 400 cars over a steering fault.
Older cabs have also been taken off the streets as part of the Mayor's clean air strategy.
