For more than a decade, the event has riled tensions between political groups, politicians and protesters in the capital, with many calling for a ban.

It comes as the conflict between Iran and the US and Israel rages across the Middle East.
Here is everything we know about the planned event:
When is the event expected to take place?
Thousands of protesters could gather outside the Home Office before marching through central London.
What route are they expected to take during the rally?
The route for 2026 is expected to take the same roads as it has in previous years.
This route begins at the Home Office on Horseferry Road before going to the Houses of Parliament, across Westminster Bridge and ending outside Downing Street.
Have there been problems at previous rallies?
Yes, and there has always been a high police presence at the annual event.
It is feared that this year could be the biggest risk yet given the ongoing conflict.
Previous editions of the event have seen protesters carrying flags of Hezbollah, the Iranian-backed Lebanese terrorist group and shout chants such as, “Death to Israel. Death to America.”
Who is calling for the rally to be cancelled?
Labour MPs have joined efforts to have the protest called off.
Lord Austin of Dudley, a former Labour MP, told The Times: “It is outrageous that supporters of Iran’s terror regime are allowed to march on Britain’s streets calling for the destruction of western democracy. I’m all for freedom of speech but this is a hate march by fans of an theocratic Islamist dictatorship that recently slaughtered 36,000 of its own citizens who dared to come out and protest against it.”
“Our police forces and the home secretary should exercise their powers and take decisive action to stop these marches from going ahead. Anyone who joins these marches and is not a British citizen should be deported immediately.”
Labour MP for North Durham Luke Akehurst said: “It’s completely inappropriate for supporters of the Iranian regime to be allowed to march through London while British forces are under attack from Iran, and risks serious public disorder.”
What have the event organisers said?
The IHRC has also been approached for comment, but in a statement online said: “The Al-Quds Day march and rally held in the UK for nearly 40 years, is a non-confessional, family oriented event that calls for justice for Palestinians. It is led by Muslim, Christian and Jewish organisations. Sadly it has been routinely demonised and targeted by Israel first politicians and media, often in totally untruthful ways.”
The group added: “Any ban on Al-Quds Day would destroy any remaining credibility that the UK has. When the world, including the vast majority of British people, are clamouring for justice for Palestine, it is perhaps best that the British government serve their interests, rather than that of a genocidal state currently unleashing further violence on Iran and Lebanon as well as Gaza.”
Has the event been cancelled?
As yet, the event is still going ahead.
A Home Office spokesperson said in a statement to The Standard: “While it is for the police to determine whether a protest risks public order and safety, we have robust legislation in place to deal with threatening, abusive, or harassing behaviour and incitement to hatred. We expect the police to use the full force of the law.
“The government has sanctioned the IRGC in its entirety, as well as more than 550 Iranian individuals and entities, and set out a robust package of measures to tackle threats from the Iranian regime.”
A spokesperson for the Metropolitan Police said: “We recognise that there will be more attention on this protest given the ongoing conflict in the Middle East. It is likely numbers will be increased and the possibility of counter protest is greater. We will keep all these matters under careful review and will publish the details of our policing plan closer to the time.
“In response to the question of a ban, it is important to recognise that the police do not have the power to ban protest. They can apply to the Home Secretary for a ban but only if there is a risk of serious disorder that cannot be managed by the use of police tactics or the imposition of Public Order Act conditions alone. That is a high threshold.
“Officers will still take a zero-tolerance approach to hate crime, including antisemitism, and support for proscribed organisations. They will intervene decisively where they see people crossing the line from lawful protest to criminality.”
