MPs demanded in a scathing report from the Home Affairs Committee last night that the Olympics security firm G4S forfeit its £57m management fee after failing to supply the required number of security staff and creating an "11th hour fiasco". It should also compensate recruits who signed up but were given no work, and be "blacklisted" from government contracts, the MPs say.
