Since the controversial ban on July 7, more than 700 people have been detained at peaceful protests.

London’s Metropolitan Police say at least 60 people will face prosecution for “showing support” for Palestine Action, the activist group outlawed as a “terrorist organisation” last month for protesting Israel’s genocide in Gaza. Three others have already been charged.

“We have put arrangements in place that will enable us to investigate and prosecute significant numbers each week if necessary,” the force said in a statement on Friday.

Since the controversial ban on July 7, more than 700 people have been detained at peaceful protests, including 522 arrested at a protest last weekend for holding signs backing the group, believed to be the largest number of arrests at a single protest in the capital’s history.

Critics, including the United Nations, Amnesty International and Greenpeace, have called the ban an overreach that risks stifling free speech.

Director of Public Prosecutions Stephen Parkinson said the latest decisions were the “first significant numbers” from recent demonstrations, adding: “Many more can be expected in the next few weeks. People should be clear about the real-life consequences for anyone choosing to support Palestine Action.”

The UK’s Equality and Human Rights Commission has also warned against a “heavy-handed” approach, urging the government and police to ensure protest policing is proportionate and guided by clear legal tests.

The initial three prosecutions earlier this month stemmed from arrests during a July demonstration, with defendants charged under the Terrorism Act. Police said convictions for such offences could carry sentences of up to six months in prison, along with other penalties.

Metropolitan Police Commissioner Mark Rowley praised the rapid coordination between officers and prosecutors, saying he was “proud of how our police and CPS teams have worked so speedily together to overcome misguided attempts to overwhelm the justice system”.

Home Office Minister Yvette Cooper defended the Labour government’s decision to proscribe Palestine Action, stating: “UK national security and public safety must always be our top priority. The assessments are very clear, this is not a non-violent organisation.”

The group was banned days after claiming responsibility for a break-in at an air force base in southern England, which the government claims caused an estimated 7 million pounds ($9.3 million) in damage to two aircraft. The home office has accused it of other “serious attacks” involving “violence, significant injuries and extensive criminal damage”.

Palestine Action has said its actions target the United Kingdom’s indirect military support for Israel amid the war in Gaza.

The UK’s Liberal Democrats voiced “deep concern” over using “anti-terrorism powers” against peaceful protesters.

Hundreds of thousands of people have demonstrated in several UK cities for nearly two years, calling for an end to Israel’s war on Gaza and for the British government to stop all weapons sales to the country.

Prime Minister Keir Starmer said last month that the UK will recognise the state of Palestine by September unless Israel takes “substantive steps” to end its war on Gaza and commits to a lasting peace process. Many who have been protesting to end Palestinian suffering have said the move is too little, too late.
