325 People Arrested At Palestine Action Protest — UK Police

The London protest was a large demonstration supporting Palestine Action, held outside the US embassy. It took place before the UK Supreme Court’s appeal hearing on the government’s decision to ban the group. The protest matters because expressing support for Palestine Action can now lead to arrest under the Terrorism Act.

Police said 325 people were arrested on the Saturday protest. Of these, 320 were arrested for expressing support for a proscribed organization. The remaining five arrests were made for other reasons, although the article does not specify them. Demonstrators described the event as a “mass action.”

The arrests show how directly the ban affects public demonstrations. The Supreme Court hearing is due to last two days from Wednesday. Meanwhile, police continue reviewing evidence from related protests, including a smaller rally in Edinburgh where no arrests were made at the time.

Palestine Action is an organization at the center of a legal and political dispute in Britain. The article identifies it as a group that the UK government outlawed under anti-terror legislation in July 2025. It does not provide further details about the group’s goals, structure, or activities.

The ban places Palestine Action on a blacklist alongside entities including Palestinian militants Hamas. Because of that status, the law treats membership in, or support for, the group as a criminal matter. This is why protesters were arrested for displaying support, rather than simply for attending a rally.

The group’s status is being challenged in court. The UK Supreme Court is holding a two-day hearing on the government’s decision from Wednesday. Until the appeal is resolved, police say they will continue enforcing the proscription and reviewing evidence from demonstrations.

Under the UK system described here, proscribing an organization means formally outlawing it under anti-terror legislation. The organization is placed on a blacklist alongside entities such as Palestinian militants Hamas. This is far more serious than treating it as an ordinary political group or protest cause.

The designation changes what supporters can legally do. For Palestine Action, the article says membership or support became a crime. That includes publicly expressing support, which police used as the stated basis for 320 arrests at the London demonstration. The article also says the possible punishment can reach 14 years in prison.

The designation remains contested. The government made its decision in July 2025, while the Supreme Court is reviewing it in a two-day hearing. The case will examine the ban’s legal status as enforcement continues against people showing support.

When a group is proscribed under the Terrorism Act, actions that express membership or support can become criminal. In Palestine Action’s case, the article specifically says membership of, or support for, the group is an offense. That reaches beyond the conduct of the organization itself and affects people who publicly identify with it.

Police arrested 320 London protesters for expressing support for a proscribed organization. In Edinburgh, officers said they were reviewing evidence involving people wearing supportive T-shirts and holding supportive banners. Police Scotland said further action could follow after that review, although no arrests had been made there at the time.

The stated maximum punishment is 14 years in prison. More than 4,000 people have been arrested since the designation, according to campaigners and police tallies. The Supreme Court’s review could become important for how such support is treated in future, but the article does not state its eventual outcome.

The Supreme Court is reviewing whether the UK government’s decision to proscribe Palestine Action under anti-terror legislation should stand. The government made the decision in July 2025. The appeal matters because the designation makes membership or support for the group a criminal offense, with a possible prison sentence of up to 14 years.

The case follows widespread enforcement. Police arrested 325 people at a London protest held ahead of the hearing, including 320 for expressing support for a proscribed organization. Campaigners and police tallies say more than 4,000 people have been arrested since the ban, including senior citizens and Holocaust survivors.

The court is scheduled to hold a two-day hearing from Wednesday. The article does not give the legal arguments or predict the judgment. Its review will nevertheless occur while police continue examining evidence from protests, including possible support shown at an Edinburgh rally.

Enforcement of the ban has been extensive. Campaigners and police tallies say more than 4,000 people have been arrested for showing support for Palestine Action. The arrests are not limited to a narrow group: the article says many senior citizens and Holocaust survivors are among those detained.

The latest example came in London, where police arrested 325 people at a protest outside the US embassy. They said 320 arrests were for expressing support for a proscribed organization. In Edinburgh, a smaller rally produced no arrests at the time, but police were reviewing people seen in supportive T-shirts and holding banners.

That review means further action remains possible in Scotland. The continuing arrests show that the ban is being actively enforced while its legality is challenged. The Supreme Court’s upcoming hearing may affect the dispute, but the article gives no indication of the court’s likely decision.

Restricting an organization under counterterrorism law is different from regulating an ordinary protest. Ordinary protest rules generally focus on conduct, such as public order or safety. Proscription goes further by making membership or support for the organization itself a crime. In this case, police arrested people for expressing support, including through protest activity.

The article shows the mechanism clearly. Palestine Action was placed on a terrorism blacklist, and supporters could face up to 14 years in prison. Police said 320 London arrests involved expressing support for the group. In Edinburgh, officers reviewed T-shirts and banners for possible evidence of support.

This creates a tension between public safety and freedom of expression. Counterterrorism law is intended to address serious threats, while expression protects people’s ability to voice political views. The article does not present the court’s arguments or ruling. The Supreme Court’s review will determine the next stage of this contested balance.
