Palestine Action supporters arrested as London’s Met Police reverse policy 

London’s Metropolitan Police have arrested 18 supporters of Palestine Action, days after the force promised to resume arrests in a reversal of policy.

The protesters had sat on the steps of New Scotland Yard, the Met’s headquarters, on Saturday, holding signs that read: “I oppose genocide. I support Palestine Action.”

Officers made the arrests under “terrorism” legislation.

Following the High Court’s ruling in February that banning Palestine Action as a “terrorist group” was unlawful, the force had said it would adopt a “proportionate approach” and stop arresting the group’s supporters and focus instead on gathering evidence.

But on Wednesday, Deputy Assistant Commissioner James Harman had said that since any “impact of that judgement will not take effect until the government’s appeal has been considered, which could take many months”, it would resume arrests. “We must enforce the law as it is at the time, not as it might be at a future date,” he said.

As she was led away by two officers on Saturday, one woman, in footage posted to social media, can be heard saying: “I’m being arrested for holding a cardboard sign, whereas our government feels the need to sell weapons and use our airbases to commit genocide in Palestine.”

Critics say the Met’s U-turn defies the court ruling.

Palestine Action is a direct action campaign group which has targeted weapons manufacturers linked to Israel and an RAF base.

The government proscribed it as a “terrorist organisation” in July 2025, placing it alongside groups including al-Qaeda and Hezbollah. The High Court called the move “disproportionate”  and in breach of freedom of expression.

The government was granted a stay pending an appeal, meaning the ban technically remains in force.

Home Secretary Shabana Mahmood, who said she would fight the High Court ruling in the Court of Appeal, said in February that supporting Palestine Action was not the same as supporting the Palestinian cause.

Chief Magistrate Paul Goldspring has since ordered that hundreds of related prosecutions be paused until after that appeal is heard.

Nearly 3,000 people have been arrested for holding signs in support of the group, contributing to a 660 percent rise in UK “terrorism” arrests in the year to September 2025, Defend Our Juries said.

On the day of the High Court ruling, about 150 people held the same placards outside the court and not a single person was arrested.

The scale of the crackdown has drawn sharp international criticism, including from the UN.

When the ban was first imposed, UN Human Rights Chief Volker Turk said it appeared “disproportionate and unnecessary”, warning it risked criminalising the legitimate exercise of free expression.

In January, US Undersecretary for Public Diplomacy Sarah Rogers told the news platform Semafor that “censoring that speech does more harm than good”.

Amnesty International, which intervened in the court case, said thousands had been “arrested for something that should never have been a crime.”

Eight activists linked to the group staged a lengthy hunger strike in prison, with four held on remand for 15 months before being bailed in February. Four others remain imprisoned.

Earlier this week, Al Jazeera reported that released detainees are now pursuing legal action against the prisons over alleged mistreatment.

Defend Our Juries has called a mass sign-holding event, titled Everyone Day, at Trafalgar Square on April 11, as the government’s appeal heads to court.

Saturday’s arrests took place as the rest of the city was filled with demonstrators who came out to march against the far right.
