The 309th Birmingham group based at Green Lane mosque in London and the 466th Manchester group based at Khizra mosque also flout the co-education policy.
The mosques have been referred to the police along with three others under investigation by the Scouts – the East London Mosque, which hosts the Rashidun Scouts Group, the As-Suffa Institute, which hosts the 327th Birmingham Scout Group and the Cheadle Mosque hosts the 4th Heald Green CMA Scout Group.
Nikita Malik of the Henry Jackson Society told the Telegraph: “The MAB has been a long-time proponent of Islamism in the UK and should not be in a position to host a Scout group.
“Hussain Al-Rawni, its Scout leader in the UK, has a social media presence that propagates support for the network, and promotes dangerous terror-denying conspiracy theories and praises anti-Semitic organisations. This man should categorically not have access to children.”
A spokesman for the Scouts said: “The safety of our young people is our number one priority and we take all safeguarding allegations with the utmost seriousness.
“We are opposed to extremism in any form. As a result of this information we have suspended a volunteer and launched a full investigation. We are carrying out a thorough review of our rules and guidance on the appropriateness of Scout meeting places to give further clarity to our volunteers.”
The Muslim Association of Britain did not respond to a request for comment.
