On July 5, 2025, UK authorities arrested 27 protesters in central London during a demonstration supporting Palestine Action, a pro-Palestinian activist group recently banned and designated as a terrorist organization under the UK's Terrorism Act 2000. The arrests followed the enforcement of the ban, which came into effect after a failed Court of Appeal challenge to prevent the proscription. The Metropolitan Police detained the protesters on suspicion of terrorism offenses. Among those arrested was 83-year-old Reverend Sue Parfitt, a retired priest from Bristol, who was taken into custody for holding a placard stating, "I oppose genocide. I support Palestine Action." The group had been targeted by the UK government following activist actions that included damaging planes at a Royal Air Force base to protest military support for Israel. The arrests have raised concerns about freedom of expression amid the government's crackdown on pro-Palestinian activism.
