Hundreds of additional police officers being brought in from across the country to bolster resources in London ahead of a weekend protests and events.
Around 500 supporters of Palestine Action plan to defy a ban on the terror group during a demonstration in Parliament Square on Saturday.
Scotland Yard has warned anyone taking part in the demonstration organised by Defend Our Juries they face arrest.
But on Friday afternoon, officers will be deployed in the vicinity of hotels being used to accommodate asylum seekers in Islington and in Canary Wharf in anticipation of possible protest and counter demos.
They plan to also be policing a number of local events in opposition to continued Israeli military action in Gaza across Tower Hamlets and Putney.
Last week in Westminster, a protest organised by the same International Jewish Anti-Zionist Network saw 36 arrests after a breakaway group attempted to block the road at Oxford Circus.
Adding to the “rapidly shrinking” force’s headache, the latest national demonstration by the Palestine Coalition, made up of the Palestine Solidarity Campaign, Stop the War and other groups, will march from Russell Square to Whitehall followed by an assembly with speeches on Saturday.
PSC director Ben Jamal vowed the fight is being taken to Prime Minister Sir Keir Starmer’s “doorstep” in Downing Street, alleging: “Our government must stop arming Israel, end all military cooperation, end all trade with Israel and introduce a full body of sanctions on this genocidal state.”
Metropolitan Police Deputy Assistant Commissioner Ade Adelekan, who will lead the policing operation, said: “This is going to be a particularly busy few days in London with many simultaneous protests and events that will require a significant policing presence.
“I’m grateful not just to the Met officers who will be working incredibly hard over the coming days but to those colleagues from other forces who have been deployed to London to support us.
“Our role in the context of protest remains as it always has been – to police without fear or favour, to enforce the law, to keep the peace by ensuring groups with opposing views do not come together and to prevent serious disorder and serious disruption to ordinary people going about their lives.
“There is no doubt that the scale of the public order policing operation will put pressure on our resources, but Londoners can be assured that we have plans in place that will allow us continue to police in communities across all 32 boroughs, responding to emergencies and keeping the public safe.”
On Sunday, as well as the FA Community Shield match between Liverpool and Crystal Palace at Wembley, from 3pm there will be a “National March for the Hostages” in central London organised by Stop the Hate and a number of Jewish organisations.
Officers will again be deployed at the Britannia International Hotel in Canary Wharf 48 hours on from Friday night.
A total of 221 people have been arrested at a wave of protests across the UK in response to the proscription of Palestine Action last month. Ten are charged with offences under the Terrorism Act.
The organisers of Saturday’s demonstration, Defend Our Juries, said protests will continue until a High Court challenge over Palestine Action’s ban in November.
The move to ban them came after two Voyager aircraft were damaged at RAF Brize Norton in Oxfordshire on June 20, which police said caused about £7 million worth of damage.
Home Secretary Yvette Cooper announced plans to proscribe Palestine Action three days later, saying the vandalism of the planes was “disgraceful” and the group had a “long history of unacceptable criminal damage”.
