Supporters of the party were also urged to "exercise caution" and asked not to take Labour Party banners to demonstrations.

An email, shared with Sky's deputy political editor Sam Coates, says the party's advice is in the interests of safety and to prevent colleagues from sharing a platform with "individuals that threaten to undermine the values and principles of the Labour Party".

When explaining why they should not take party banners, David Evans, Labour's General Secretary, said: "Individuals will not have the ability to control who they are photographed alongside and this risks threatening the Labour Party's ability to campaign against any form of racism and discrimination."

The party's position triggered a backlash among some of its members, though.

One long-term Labour member told Sky News: "It's a shocking mindset where a once proud internationalist Labour Party is now shutting down any solidarity lest it gets in the way of Labour's almost certain general election win next year."

While the email does not specify which specific protests the party was concerned about, thousands have taken to the streets this weekend against the backdrop of the escalating conflict between Hamas and Israel.

Earlier this week, Labour leader Sir Keir Starmer called the actions of Hamas "terrorism" and said "Israel has the right" to withhold power and water from Palestinian civilians.

Some in the party fear this has caused Labour to lose support among Muslim voters, and two Oxford councillors resigned in the wake of the comments.

Keir Starmer MP, Leader of the Labour Party, said in a statement on Saturday evening: "A week ago we awoke to the unimaginable and heartbreaking news of terrorist attacks on Israel from Gaza by Hamas.

"In the days that have followed we have heard horrific stories of the murder and mutilation of men, women and children, along with the horror of hostage taking. Israel has the right, indeed the duty, to defend herself and rescue these hostages. Responsibility for what has happened sits with the terrorists of Hamas; and we repeat our call for Hamas to release all hostages.

"I've met with members of the British Jewish community this week and told them that we stand with Israel and with them at this time. I know this is a distressing and worrying time and welcome the extra funding for the CST. There must be zero tolerance of any increase in antisemitism or islamophobia.

"Hamas has no interest in peace. No interest in protecting Palestinians.

"We call on all parties to act in line with international law, including allowing humanitarian access of food, water, electricity and medicines to Gaza and ensuring safe humanitarian corridors in Gaza for those fleeing violence.

"Seven days on from the darkest day in Israel's recent history, our resolve in the face of terrorism will not falter."

Thousands take to the streets

More than a thousand officers have been deployed in London, as the Metropolitan Police warned anyone showing support for Hamas - which is a designated terror organisation in the UK - faces arrest.

Earlier this week, Home Secretary Suella Braverman said waving a Palestinian flag on British streets "may not be legitimate" if it is done to show support for acts of terrorism

It comes as civilians continue trying to flee northern Gaza after Israel's military told them to evacuate ahead of an expected ground invasion.

It follows last weekend's deadly surprise assault on Israel by Hamas insurgents.
