The lawyer representing Shamima Begum recently called for a former Home Secretary to be sent to a “concentration camp”, it has emerged.

Tasnime Akunjee, who acts on behalf of the jihadi bride, also appeared to suggest 9/11 was an inside job during controversial posts on social media seen by the Telegraph.

During his legal career Mr Akunjee has represented a number of extremists and has links to Cage, the group once described by Boris Johnson as being “apologists for terror”.

Last month he shared a post on his Facebook page suggesting that the 9/11 attack may have been a “controlled demolition” rather than a terrorist act carried out by Muslims.

In another post about former home secretary Amber Rudd he wrote: “Pls God some how arrange for this person to find herself in a concentration camp.”

He has also argued for a ban on products decorated with the Union Jack because “Brits killed millions of Europeans.. Turks.. Iraqis”. Writing about major wildfires that killed dozens of people in the US last year, he suggested: “If this doesn’t look like a punishment from God I don’t know what does.”
