Workers from some of the capital's poorest communities may not benefit from the jobs created by the 2012 Olympic Games, a London Assembly committee has warned.
According to the economic development, culture, sport and tourism committee report, people living in the five east London boroughs surrounding the Olympic park face "very real threats" which could see them miss out on thousands of new jobs and training opportunities.
The government has insisted that the Games will create a "legacy of regeneration".
And London's Employment and Skills Taskforce and the London Development Agency (LDA) have said the Olympics will see up to 50,000 new jobs in the Lower Lea Valley.
This will include 12,000 in the Olympic Park and more in the run-up to the Games.
However committee chairman Dee Doocey said locals could miss out unless language and construction skills were "urgently" improved in the east London boroughs.
She said: "The last thing we need is another Docklands, where many of the newly created jobs did not benefit local people."
"We need to get this right from the very start," she added. "Otherwise we risk losing the truly life-changing potential of the Games for local people."
Responding, the LDA pledged to make it a "priority" to ensure locals in the neighbouring boroughs of Greenwich, Hackney, Newham, Tower Hamlets and Waltham Forest benefit from the new opportunities.
A spokesman said: "We are actively seeking to prepare local people for these jobs and ensure a lasting legacy for Londoners through targeted, industry relevant skills and employment support.
"Many of our programmes are already under way and their impact will increase as more are rolled out."
Of the 720,000 people of working age living in the neighbouring Olympic areas, a quarter have no qualifications and over 60 per cent are unemployed.
