Several hundred taxi drivers brought traffic on Blackfriars Road to a halt on Thursday lunchtime in a protest outside the offices of Transport for London.
The protest by members of the London Cab Drivers Club began outside 230 Blackfriars Road – where TfL's taxi and private hire department is based – and moved to the Palestra office block opposite Southwark Underground Station.
Drivers carried placards alleging corruption at TfL and calling for a public inquiry into the transport authority and its handling of minicab licensing in the age of Uber and similar apps.
Protesters also handed out flyers to passers-by highlighting perceived risks to minicab passengers' personal safety.
The LCDC members also visited the studios of talkSPORT in Hatfields.
