The Met Police has imposed conditions to separate protesters marking a week since the Manchester synagogue terror attack and pro-Palestine activists.
A protest organised by the Campaign Against Antisemitism (CAA) will begin in Whitehall at 7pm on Thursday, marking a week since the terror attack at Heaton Park Hebrew Synagogue in Crumpsall, Manchester.
Father-of-three Melvin Cravitz, 66, and Adrian Daulby, 53, were killed during the attack last Thursday.
Jihad Al-Shamie, 35, rang 999 during his deadly rampage, pledging allegiance to the so-called Islamic State terror group.
He drove his car at Jews gathering for the holy day of Yom Kippur then attacked others with a knife and tried to storm the synagogue, wearing a fake suicide belt, before being shot dead by armed police.
It comes after a vigil was held earlier on Thursday outside the Heaton Park Hebrew Synagogue where dozens of local Jews, some with arms linked or hugging, paid tribute to the victims.
Ahead of the CAA protest in central London, the Met Police said it will have officers nearby to keep attendees safe and to respond to any incidents.
The force said on Thursday it had also become aware of plans by a number of pro-Palestinian groups to also gather in Whitehall at the same time as the CAA protest.
The Met explained that while there was no indication that the pro-Palestinian protests will directly counter the CAA, “it is our judgement that the coming together of large groups with opposing views in the same location poses a risk of serious disorder”.
Public Order Act conditions have been introduced to prevent anyone taking part in the pro-Palestinian protests from assembling in a specific area around Whitehall.
Further conditions have also been imposed to prevent the pro-Palestine protesters from gathering around Great Portland Street and Portland Place as it is close to a synagogue.
The Met warned anyone breaching the conditions or encouraging others to do so could be arrested.
It comes as police are to be given greater powers to restrict protests by allowing them to consider the “cumulative impact” of repeated demonstrations.
The measures follow frequent pro-Palestinian demonstrations, including in London last Saturday, despite calls for restraint following the synagogue attack.
Almost 500 people were arrested, the majority for supporting the banned terror organisation Palestine Action.
Home Secretary Shabana Mahmood has said repeated large-scale protests had caused “considerable fear” for the Jewish community.
The Government will amend Sections 12 and 14 of the Public Order Act 1986 to explicitly allow the police to take account of the cumulative impact of frequent protests on local areas to impose conditions on public processions and assemblies.
