Traffic at the Elephant & Castle was brought to a near standstill on Monday afternoon when taxi drivers converged on the junction to launch a week-long series of protests against Transport for London's handling of Uber's private hire licence.
The protest was organised by the Independent Taxi Alliance which describes itself as a "proactive umbrella group formed to highlight corruption through legitimate protest".
The black cab campaigners complain that Uber is able to continue to operate in London whilst the company appeals against TfL's decision not to renew its licence.
Bus services were curtailed or diverted away from the Elephant, leaving dozens of pupils from Notre Dame RC Girls' School wondering how they were going to get home.
Further protests are planned every afternoon this week, including a demo at London Bridge on Thursday.
