More than 500 people were arrested during a mass protest in Trafalgar Square, London, opposing the ban on the activist group Palestine Action.
Demonstrators, including Massive Attack’s Robert Del Naja, held signs such as "I oppose genocide. I support Palestine Action" and were detained for supporting a proscribed organisation.
The ban on Palestine Action was ruled unlawful in February, but remains in place pending appeal, raising concerns about free speech and the right to protest in the UK.

UK Government’s Terrorism Proscription of Palestine Action Sparks Legal Battle and Over 3,000 Arrests
Overview
In July 2025, the UK government proscribed Palestine Action as a terrorist group, leading to over 700 arrests under terrorism laws. However, the High Court ruled this ban unlawful in February 2026, citing it as a disproportionate attack on legitimate protest. Despite this, the government appealed and police resumed enforcing the ban, resulting in mass arrests, including 212 protesters at the April 11 Trafalgar Square demonstration, where elderly participants faced harsh treatment. Human rights groups condemned these actions as an erosion of civil liberties. The upcoming Court of Appeal decision will determine the future of protest rights and the legal status of thousands caught in this contentious crackdown.
