The UK government has moved to proscribe the activist group Palestine Action as a terrorist organization under the Terrorism Act 2000. This decision followed a parliamentary vote on July 2, 2025, in which Members of Parliament approved the ban by 385 votes to 26. The move was prompted by incidents involving Palestine Action activists, including the vandalism of two Royal Air Force planes at Brize Norton and blockades of Israeli arms companies' UK headquarters. The proscription makes it a criminal offense punishable by up to 14 years in prison to be a member of or support Palestine Action. Prior to the parliamentary vote, Palestine Action sought a legal challenge to prevent the government from banning the group, with co-founder Huda Ammori, of Palestinian and Iraqi heritage, applying for interim relief to suspend the proscription. However, the UK High Court rejected the group's bid to temporarily block the designation. The court granted Palestine Action an urgent hearing to consider a judicial review, but ultimately a judge denied the request for a temporary injunction. The ban is expected to take effect following approval by the House of Lords. Palestine Action has stated that the decision is unlawful and intends to challenge it further. The designation places Palestine Action alongside other proscribed groups such as ISIS and the IRA.
