The report into Islamic charities will be an early challenge for Baroness Stowell, the newly-appointed chairwoman of the Charity Commission.

Islamic charities vulnerable to extremists receive £6 million a year from taxpayers in gift aid, according to a new report.

The charities are accused of promoting hardline speakers by giving them platforms, spreading their literature, providing them with credibility and enabling access to beneficiaries and the general public.

The report accuses charities of supporting “the spread of harmful non-violent extremist views that are not illegal; by providing platforms, credibility and support to a network of extremists operating in the UK.”

One international charity mentioned in the paper is chaired by an Islamic preacher banned from entering the UK.
