Traffic in Blackfriars Road was halted on Monday morning as minicab drivers protested outside Transport for London's offices over plans to remove their congestion charge exemption.
The Mayor of London and TfL announced just before Christmas that private hire drivers will lose their exemption from the congestion charge with effect from 8 April, as part of a package of measures to tackle the capital's poor air quality.
The protest was organised by the Independent Workers Union of Great Britain's United Private Hire Drivers branch.
Abdurazk Hadi, Uber driver and chair of the London committee of the IWGB's UPHD branch said: "Drivers like myself, already suffering from Uber's poverty wages, are now being hit by this ill thought out congestion charge.
"Instead of targetting the pockets of multinational corporations, Sadiq Khan has chosen to introduce this tax on the poor, leaving us no option but to protest.
"Unless this charge is scrapped many of us don't know how we will continue feeding our families and paying for a roof over our heads."
