Claims that vulnerable asylum seekers have been evicted from their homes after failures by contractors working for G4S, the world's biggest private security firm, are to be investigated by a parliamentary watchdog. At least three women are alleged to have been expelled from properties because of rent arrears that had arisen because G4S subcontractors had not paid landlords. A letter from Margaret Hodge, chair of the public accounts committee, seen by the Observer, admits that the Home Office "is aware of general concerns around the contracts in operation" and that a review into asylum accommodation by the NAO will form part of a wider look at the delivery of public services by private sector contractors, including G4S. (Mark Townsend, The Observer, 21 July 2013)
