Tory ministers are facing possible legal action over an asylum centre housing 3,500 people in conditions described as "dire" by senior MPs.
Immigration Minister Robert Jenrick last night confirmed the Government had received "initial contact for a judicial review" over the Manston facility in Kent.
Mr Jenrick claimed the move was "not unusual" as it concerned a "highly litigious area of policy" - but did not reveal who was behind the challenge.
