The number of people from East London working on the 2012 Olympics construction site has now reached one-in-four of the workforce.

More than 3,000 of the 12,635 workers come form the five ‘host’ boroughs, said to be above the ‘target’ of at least 15 per cent, latest Olympic authority figures show.

They live in Tower Hamlets and neighbouring Hackney, Newham, Greenwich and Waltham Forest—more than six out of 10 Olympics workers are from London.

There is also more training, with nearly 4,000 places being created at the National Skills Academy which also finds job placements elsewhere in the ‘host’ boroughs to match trainees with vacancies. Total jobs filled so far through the academy is 1,473 since 2008.
