London Underground at complete standstill as thousands of workers support strike

London Underground was at a standstill today as thousands of workers solidly supported a strike, causing travel chaos across the capital.

Commuters packed on to buses or walked to work in bright sunshine, with Tube services set to be disrupted until tomorrow morning.

Business groups said the strike will cost the capital's economy tens of millions of pounds. The Government and London mayor Boris Johnson condemned the action but unions said LU was to blame.

Picket lines were mounted outside Tube stations by members of four trade unions involved in the action in a row over the new all-night Tubes, due to start in mid-September.

LU's boss warned that the strike will cause big disruption and branded it "totally unnecessary".

Managing director Mike Brown said in a message to passengers that the company had strained every muscle to put together a remarkably fair pay offer for the introduction of the new Tubes.
