Hundreds of passengers have been led through London Underground's tunnels after a power failure left them stuck on Tube trains for more than two hours.

Passengers were taken off five stalled Jubilee Line trains as a result of the outage around Baker Street station in central London at 0852 BST.

Transport for London (TfL) apologised to passengers, the last of whom reached a station at about 1130 BST.

The Jubilee line is suspended between Waterloo and West Hampstead.

Commuters and other travellers had to walk for 20 minutes along a Jubilee Line track lit only by staff carrying torches.

"A few passengers were getting very agitated and the air in the carriage was quite stale after such a long wait," said commuter Bartolome Molina.

A TfL spokesman said: "London Underground would like to apologise to customers whose journeys were disrupted this morning particularly those who were on the stalled trains. An investigation is currently under way to establish the cause of the power failure."

London Underground (LU) said it expected services on the Jubilee Line to be running again later on Monday.

About 400,000 passengers use the Jubilee Line each day.

There was also major disruption on the Central and Metropolitan lines and minor delays on the District, Northern and Piccadilly lines on Monday morning.

The Rail Maritime and Transport union said these were due to industrial action about a row over job cuts.

The union has imposed an overtime ban on its members.

But LU said the only line affected by the industrial action was the Metropolitan.
