New research shows the number of people working from home has risen by 50 per cent during the Olympics.

A study of 2,000 adults in London and the South East found those working flexibly had increased by a third.

Four out of five said they would work flexibly at some point during London 2012, varying their hours to travel later or earlier than usual.

Researchers found that around four million people would work from home or "al desco" over the two weeks.

The figures may go some way to explaining why parts of the capital have been much quieter than expected since the Games began.

The report claimed that the change in working arrangements has already taken a huge burden off London's transport network.
