The fourth tube strike in three months started at 6.30pm tonight but many lines are still running normal services and London Underground hopes to continue to do so throughout Monday.

Transport for London say that the DLR, London Overground and other rail services will be operating as normal, as will bus and river bus services where there will also be some extra services operating.

Passengers are advised to check www.tfl.gov.uk for the latest information and drivers are reminded that the congestion charge is still in place during the strike.
