G4S bids for Commonwealth Games contracts after Olympics "shambles" G4S, the world's largest security services firm, who admitted its handling of the London Olympics was a "humiliating shambles," has reportedly bid for a contract for the Commonwealth Games in Glasgow next year. The company failed to provide enough security staff for its London 2012 contract, meaning the British Army had to step in at the last minute. It paid £70 million (€81m) to London 2012 organisers in compensation. Organisers of the Commonwealth Games have chosen to break up the security contracts, so they are not reliant on just one provider. G4S has so far not commented on the contract. It comes after the firm denied allegations its employees abused inmates at a prison it ran in South Africa.
