Commuters were being urged to take a day off work or to stagger their journeys, as the RAC warned that the strike could paralyse London. Roads used by tens of thousands of commuters from the Home Counties and Hertfordshire are expected to be up to a third busier today.
London Underground will offer a reduced service but many workers will be obliged to use packed overground trains or join jammed roads.

A spokesman for Scotland Yard said: "There have been dreadful situations in years past and we will police it as best we can."
