Commuters will continue to face delays despite Tube staff returning to work after the end of the firefighters' strike.

London Underground (LU) has said the 22 stations closed on Friday because the industrial action re-opened at 1800BST.

LU added it expects a full roster of staff, after 81 drivers refused to work on Friday over safety concerns during the firefighters' stoppage.

About 100 staff did not work on the first day of the strike on Thursday.

Restricted services

But LU warned that although services will continue to improve, passengers should not expect a normal service until Saturday morning.

During the strike on Friday, the Circle line was suspended and restricted services were running on the Bakerloo, Piccadilly, Victoria, Northern and Hammersmith and City lines.

But the Waterloo and City line, which was suspended on Thursday, was working normally.

A military spokesman said it had received 1,016 calls over he 48 hours of the stoppage.

Calls over the strike period

Total calls, 1,016 Hoax calls, 154 Responded to, 632

Of those 154 were hoaxes and it responded to 632 of them.

He said the proportion of hoax calls received at London's control centre was not much higher than normal.

But because of the limited resources available the hoaxers would have a bigger impact on emergency fire cover.

He said: "Our aim, and we were tasked with, providing an emergency firefighting service, primarily to save life and in the London area over the 48 hours we had a huge number of calls.

"Nobody lost their lives and no fire was still burning when we finished and we consider we succeeded in our aim."

There were no major incidents in London overnight, but in the early hours of Friday emergency crews were called to a road accident in Woodford Green where the Army cut two people free from their vehicles.
