Question to the Home Office:

To ask the Secretary of State for the Home Department, how many people have been arrested for being a supporter of (a) the Maniacs Murder Cult, (b) Palestine Action and (c) the Russian Imperial Movement since the passing of the Terrorism Act 2000 (Proscribed Organisations) (Amendment) Order 2025.

The Government is absolutely clear that support for proscribed organisations is unacceptable. Anyone expressing support for a proscribed organisation should expect to be investigated by the police.

The Home Office releases statistics which cover arrests for terrorist-related activity on a quarterly basis. It would not be appropriate to provide a running commentary on arrests relating to proscribed organisations.

On Palestine Action specifically, the Metropolitan Police Service has also released statistics on the arrests made at the central London protests on 9 August 2025 and 6 September 2025 which can be found here: https://news.met.police.uk/news/update-532-arrested-during-protest-policing-operation-499897 and https://news.met.police.uk/pressreleases/update-on-demonstration-in-support-of-palestine-action-3403168

Operational decisions, including arrests, are a matter for the police, who are independent of Government.
