Suella Braverman has said some charities are “politically motivated activists masquerading as humanitarians”, after a damning report into “misconduct” at one of the main voluntary groups opposing her Rwanda deportation flights.

In an outspoken attack, the Home Secretary targeted some charities and civil society groups for “actively undermining efforts to curb illegal migration” and being part of an “establishment” including immigration lawyers “committed to ever increasing migration”.

Her comments came after a charity commission report found evidence of “inappropriate” payments, misconduct and mismanagement at Care4Calais, a charity that played a key part in legal action which have held up the Government’s Rwanda deportation flights.

It described as “inappropriate” payments of £340,000 from the charity into the personal account of Care4Calais’ founder and former trustee Clare Moseley, an arrangement that it said put its funds at “undue risk”.

It was one of a series of historic failings at the charity including a conflict of interest between two trustees that amounted to “misconduct” and “inadequate” management of complaints including one against a trustee which was investigated by another trustee to whom they were related.
