Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment she has made of trends in the number of prosecutions of offences under the Terrorism Act 2000.

In the year ending 30 June 2025, 83 persons were tried for terrorism-related offences, an increase of 5 compared with the year ending June 2024 and 16 more than the average over the last 10 years (67). 80 of those 83 (96%) persons tried were convicted. Conviction rates have remained consistently high in recent years, with the highest conviction rate on record in the year ending 31 December 2024 (98% - 84 out of 86 trials resulting in conviction). This is a testament to the sustained efforts of CT Policing and the Crown Prosecution Service in securing record convictions for terrorism-related offences.

These statistics are routinely published by the Home Office as part of its quarterly reporting on the ‘Operation of Police Powers under the Terrorism Act 2000 and subsequent legislation’.
