In a rare move, 17 Church of England bishops have united with church leaders of other denominations to urge the government to end indefinite detention, This move followed a BBC documentary describing Brook House immigration centre as 'a toxic, brutal and a failing environment where self-harming is commonplace'. Data from the Migration Observatory showed that in the final quarter of 2016, 2,573 of the 7,078 migrants released from detention had been held for more than 28 days, and 53 had been held for over a year. In a letter to the Telegraph on 6 September, the bishops say they are 'deeply concerned' by the findings, and accuse 'some politicians and sectors of the media' of dehumanising immigrants. The complaint was organised by former G4S manager and now whistle-blower and priest, Nathan Ward.
