Black cab drivers have brought Whitehall to a standstill to call for a public inquiry into Transport for London.

Long queues of blank cabs, with some drivers honking their horns, caused gridlocked.

United Cabbies Group organised the protest.

The regulation of private hire firms, including Uber, has also sparked unrest among black cab drivers.
