Close Protection UK (CPUK), the security firm accused of using unpaid jobseekers to police the Jubilee celebrations, has contracts to provide security at the Olympics.
A spokesman for CPUK has claimed that the work experience was given to jobseekers as a trial before receiving paid work during the Olympics.
The former deputy prime minister John Prescott has called for a review of the company's Olympic contract, saying: "It would be completely inappropriate for a company that appears to have such a blatant disregard for the care of its workers to be policing such a prestigious event."
