Road users are being urged to avoid central London during a protest by thousands of taxi drivers today.
Thousands of black cab and licensed taxi drivers are set to block roads for hours after driving slowly through the capital from Trafalgar Square.
The row has flared over the introduction of a phone app called Uber which allows customers to book and track vehicles.
Unions and groups representing taxi drivers are warning that the move is leading to unlicensed drivers being contacted via the new technology, with no checks on whether they are legitimate.
Legal action is being taken against Transport for London (TfL) but drivers are taking direct action, starting with today’s protest.
