UK terrorism arrests surge past historical levels following Palestine Action ban
Official data reveals nearly half of all counter-terrorism arrests in Great Britain since 2001 occurred in the year ending March 2026, driven by protest crackdowns.
The short version
- UK Home Office data shows 3,021 terrorism-related arrests occurred in the year ending 31 March 2026, accounting for nearly half of the 6,539 total terror arrests recorded in Great Britain since 11 September 2001.
- The 1,434% year-over-year surge follows the July 2025 proscription of direct-action protest group Palestine Action under the Terrorism Act, leading to widespread arrests at peaceful demonstrations.
- Human rights advocacy groups and legal campaigners criticise the broad definition of terrorism, while the Home Office maintains that supporting a proscribed group is illegal and police act independently.
- A legal challenge against the proscription of Palestine Action is scheduled to be heard by the UK Supreme Court on 4 November.
