Transport for London (TfL) has suspended all road user charging schemes in the capital until further notice.
Mayor Sadiq Khan says the move has come to allow critical workers to travel in the city more easily. It applies to the Congestion Charge, Low Emission Zone and the Ultra Low Emission Zone.
Meanwhile, Mr Khan says that while buses continue to run in London, people should not travel unless they have no option. Passenger numbers have greatly reduced and services have been cut to match. The night bus network continues to operate.
