A man described in intelligence assessments as a leading figure in Islamist extremist circles has lost a legal challenge over the Home Office’s refusal to grant him British citizenship, but remains in the United Kingdom, according to court documents seen by GB News.
The man, referred to in proceedings only as CT to protect his identity, first came to the attention of the security services in the mid-2000s. Born in Iraq in 1976, he had lived in Britain for many years before applying to become a naturalised citizen in 2021. Court documents show he has five children, three of whom are British citizens. In February this year, the Home Office rejected his application, telling him he had failed the statutory “good character” test required of anyone seeking naturalisation. Officials did not disclose their full reasoning, saying it would not be in the public interest to do so.
CT challenged the decision before the Special Immigration Appeals Commission, or SIAC, the specialist court that hears immigration and nationality cases with a national security dimension. His lawyers argued there was no proper evidential basis for the refusal and that the process had been unfair, since he had never been told the full case against him. The commission has now rejected all four grounds of his challenge, ruling, in a public judgment, that the Home Secretary’s decision had a lawful basis and should stand. The judges reached that conclusion after reviewing both openly available evidence and a body of closed intelligence material that remains undisclosed to CT and to the public; SIAC also ruled that no further information could safely be released to the press. As a result, the detailed reasoning behind the refusal is confined to a separate closed judgment that neither CT nor the public is permitted to see.
The allegations underpinning the case, as set out in earlier proceedings, are extensive. According to the Security Service, CT supported the insurgency in Iraq, received terrorist training and was associated with Islamist extremists linked to Ansar al-Islam, a Kurdish militant group formed in 2001 that has maintained ties to al-Qaeda, is subject to international sanctions, and has been linked to bombings and attacks in Iraq using remote-controlled devices. He was also accused of contributing to the radicalisation of Muslims in Britain and was described as a prominent figure within extremist circles in Peterborough, where he was said to have preached hate at a local mosque and to have had criminal links.
Material said to have been recovered from CT’s home has also featured in the case. An earlier judgment quoted by the court recorded that investigators found evidence he had accessed websites advertising remote-controlled helicopters, remote-controlled cars and pinhole cameras, and that a search of the property recovered a large remote-controlled car. Those findings formed part of a wider intelligence picture that authorities relied upon when CT was made subject to anti-terror control orders.
CT has consistently denied all of the allegations against him throughout the various proceedings. Notably, a tribunal judge examining the case in immigration proceedings reached a striking conclusion of his own, stating: “From the decision we must conclude that the allegations made against [CT] have no foundation.” CT’s lawyers relied on that finding as part of their challenge to the citizenship refusal, alongside their argument that he had never been given a fair opportunity to respond to the case against him. SIAC nonetheless dismissed the appeal in full.
Because the case concerned CT’s application for citizenship rather than any separate immigration or deportation proceedings, he is understood to remain living in the UK. Neither the Home Office nor CT’s representatives have commented publicly on the outcome of the case.
