UK competition regulator raids Mitie offices in London

CMA examines emails from senior staff at outsourcer amid Home Office concerns over immigration centre contracts

Competition investigators raided the offices of outsourcer Mitie and are examining the emails of senior staff, after the Home Office raised concerns about suspected anti-competitive behaviour, the Guardian understands.

The Competition and Markets Authority (CMA) is examining the relationship between Mitie and US firm PAE, who operate a joint venture for the Ministry of Defence but were also competing to run Home Office immigration removal centres, at Derwentside, in Coutry Durham, and Heathrow.
