Two major donors to campaign group Cage have pulled funding in protest at the organisation's apparent defence of the Islamist militant Mohammed Emwazi, known as Jihadi John.
The Charity Commission revealed it had taken "robust action" to demand that the Joseph Rowntree Foundation and the Roddick Foundation would cease all current and future donations to the group.
Mohammed Emwazi, the British graduate identified in reports as Islamic State extremist "Jihadi John", tried "as much as he could" to clear his name and stop security services "harassing him", campaign group Cage said.
"He came to us after he felt he was being harassed by the security services; he felt there was pressure being put on him and he couldn't carry on with his ordinary life," Cage representative, Cerie Bullivant, told Good Morning Britain.
"We advised him to go to his MP, the IPCC - he was very, very willing to engage with the system to try and get his name cleared. He sent letters to the embassies as to why he was being barred, he tried as much as he could to work through the system."
Bullivant blamed what he called the "detached, unaccountable" security services for contributing to the radicalisation of Emwazi.
Lawyers for Mohammed Emwazi's father have told ITV News there's no evidence his son is IS killer 'Jihadi John' as "his face is covered".
Newly released audio recording of Mohamed Emwazi, aka "Jihadi John", reveals his claims that he was threatened by MI5 five years ago.
"I really think that the focus of your outrage should be people who throw gay men off cliffs", said London Mayor, Boris Johnson.
