Police made arrests at a large London demonstration supporting Palestine Action, where thousands gathered despite the organisation’s ban, escalating tensions between campaigners, government and Jewish communities.
The silent vigil in Trafalgar Square drew over 1,500 demonstrators, organisers said, protesting the UK government’s decision to proscribe Palestine Action as a terror organisation earlier this year.
The Metropolitan Police confirmed several arrests, including six individuals detained after unfurling a banner on Westminster Bridge in support of the banned group, Palestine Action.
“Officers were quickly on scene, the banner had been removed and the six people involved have been arrested for supporting a proscribed organisation,” police said in statements.
Organisers Save Our Juries, which coordinated the vigil, claimed the turnout surpassed expectations and suggested attendance could break historic records set during the 1961 anti-nuclear demonstration.

Many demonstrators held placards, while others stood silently, demanding the reversal of the government’s designation of Palestine Action, which campaigns against British involvement in Israeli arms manufacturing.
Prime Minister Keir Starmer earlier urged cancellation of the protest, urging respect for British Jews grieving after Thursday’s Manchester synagogue attack, which killed two people and shocked communities nationwide.
Jewish groups condemned the demonstration, calling it “phenomenally tone deaf” and warning that staging pro-Palestine events immediately after a terror attack risked inflaming antisemitism and deepening community divides.
Despite mounting criticism, protesters argued their vigil was peaceful, lawful, and focused on defending democratic rights to assemble, highlighting concerns about free speech erosion under counterterrorism laws.
Speakers accused the government of silencing dissent by targeting activist groups, insisting Palestine Action’s campaigns exposed complicity in war crimes by disrupting factories producing weapons exported to Israel.
Several attendees described the arrests as “political theatre,” claiming authorities were deliberately criminalising activism to intimidate citizens who opposed the UK’s foreign policy on Israel and Palestine.
Palestine Action, founded in 2020, has staged numerous direct actions, including occupying Elbit Systems factories in Britain, accusing the arms manufacturer of profiting from Israel’s occupation of Palestine.
The Home Office banned the group in July, citing links to violence and disruption, a decision hailed by pro-Israel groups but condemned by human rights campaigners as authoritarian overreach.
Amnesty International and other rights groups have repeatedly warned that broad terrorism designations risk criminalising legitimate protest, chilling free expression and undermining Britain’s democratic traditions of dissent.
Saturday’s protest saw a strong police presence, with uniformed officers surrounding Trafalgar Square, monitoring speeches, and detaining individuals accused of breaching conditions under the Terrorism Act.
Observers noted tense exchanges between protesters and police, but the event remained largely peaceful until the arrests, after which chants denouncing political repression reverberated across central London.
Videos circulated online showed officers physically restraining demonstrators while crowds shouted “free Palestine” and “defend democracy,” sparking fierce debate over policing standards and freedom of assembly rights.
Civil liberties advocates said the arrests highlighted an increasingly confrontational approach by authorities towards political activism, warning Britain risked sliding into a state of “managed dissent.”
“This protest was peaceful, yet people were arrested simply for standing with banners,” one activist said. “That is not democracy, that is authoritarian control.”
The scale of turnout surprised analysts, with reports suggesting thousands joined marches across central London, indicating widespread opposition to the government’s ban on Palestine Action.
“This is about more than one group,” another demonstrator explained. “If they can criminalise Palestine Action today, they can silence anyone tomorrow.”
Pro-Palestine solidarity movements have surged since Israel’s intensified military campaigns in Gaza, drawing sustained criticism of Western governments, including the UK, for continued support of Israel’s security policies.
Palestine Action’s tactics of direct disruption, often involving vandalism or blockades, have polarised opinion, with critics branding them extremist while supporters argue such measures are necessary to stop war crimes.
The Metropolitan Police defended its response, stating officers acted lawfully against individuals knowingly supporting a banned organisation, and pledged to continue enforcing restrictions against proscribed groups.
“This was a proscribed group, and displaying banners of support is a criminal offence,” a police spokesperson said, emphasising safety and legality guided their operational decisions.
Political commentators suggested the arrests could inflame tensions, creating further flashpoints between activists and the government while fuelling debates about democratic freedoms in modern Britain.
“The government faces a dilemma,” one analyst noted. “Suppressing protests risks radicalising activists, while allowing them risks appearing weak on terrorism and antisemitism.”
Starmer’s intervention underscored political sensitivities, as Labour seeks to balance solidarity with Jewish communities against growing public frustration with Britain’s support for Israeli arms production.
Jewish community leaders welcomed the government’s firm stance but expressed unease at the spectacle of mass arrests, warning it could fuel conspiracy theories and deepen divisions further.
Rights campaigners vowed to continue resisting what they described as draconian measures, promising more protests, legal challenges, and grassroots campaigns against restrictions on Palestine solidarity.

As arrests mounted, legal observers were dispatched to monitor police actions, ensuring detainees’ rights were upheld and documenting alleged abuses for potential challenges in British courts.
By evening, dozens of protesters reportedly remained in custody, while supporters gathered outside police stations demanding their release and chanting slogans condemning “political policing” and “state repression.”
Campaign groups announced further demonstrations across the country, signalling growing defiance against government efforts to criminalise Palestine solidarity movements and suppress their public visibility.
The unfolding standoff between campaigners and authorities suggests Britain’s political climate is entering a volatile period, with dissent increasingly framed as criminality under expanding anti-terrorism frameworks.
For many demonstrators, Saturday’s arrests marked not just a protest for Palestine but a defining moment in Britain’s democratic struggle, testing freedoms once considered untouchable.
