He is scrambling”, Mr Salice said, adding: “I don’t think our protests are extremist. I don’t see how being in favour of human lives is extremist.”The protesters said they targeted Barclays because of its alleged ties to companies supplying weapons to Israel Mr Salice, an Italian who now lives in Camden, added: “There could be one or two extremists who come into the protests. I can’t say that is impossible and luckily we have the police here, who are working with us.“They are helping us organise this protest and making sure they are safe. And whenever they see the odd person who may do something wrong, it is up to them to arrest them.”Speaking at a lectern outside Downing Street on Friday evening, Mr Sunak urged protesters to prevent extremists from infiltrating their ranks and warned of more stringent policing.The Tory leader said: “I want to speak directly to those who choose to continue to protest: don’t let the extremists hijack your marches.“You have a chance in the coming weeks to show that you can protest decently, peacefully and with empathy for your fellow citizens.”Paul Woof, 64, from Dulwich, who attended the protest with a sign that read: “Do I look like an extremist?”, called on politicians to witness the protests first-hand.He said: “These people ought to go on a march and see the sort of people who are on these marches, a lot of whom are Jewish.“It’s astonishing the rhetoric”, he said, adding: “They know it isn’t true. They are talking to their grassroots faithful to try and stir up division in this country.”Rishi Sunak giving a press conference in Downing Street on Friday In his Friday address, Mr Sunak said demonstrators should be able to “march and protest with passion” but “cannot call for violent jihad” or “call for the eradication of a state or any kind of hatred or antisemitism”.“I say this to the police, we will back you when you take action,” he said, confirming that senior police chiefs would be expected to police rather than simply manage pro-Palestine protests.In London, PSC targeted Barclays branches in Croydon, Hammersmith, Haringey, Harrow, Newham, Redbridge, Southwark, Streatham, Tower Hamlets, Willesden, and Wimbledon.It comes after the home secretary James Cleverly said pro-Palestinian protesters had “made their point” and questioned: “What are these protests genuinely hoping to achieve?”PSC has called for a boycott of Barclays because it claims the British bank holds “substantial financial ties” with arms companies supplying weapons to Israel.
