A foreign-born terror suspect has won the right to stay in Britain by keeping his name secret for 23 years.

The man, despite being twice ruled a threat to national security, has defeated repeated attempts to deport him by illegally keeping his true identity secret.

Incredibly, the courts have even granted him anonymity even though his actual identity is not known.

The man has used at least two false names, “Nolidoni” and “Pierre Dumond”, since illegally entering the UK in 1993 and claiming asylum. Court documents refer to him only as suspect “B”.
