The decision by the Supreme Court comes after police arrested 117 people at a protest outside Westminster Magistrates' Court on Thursday for expressing support for the group.

Five Court of Appeal judges said in June the ban on the group was "justified and proportionate".

It overturned the earlier judgment of three High Court judges who ruled in February that Yvette Cooper's decision to ban Palestine Action was unlawful, following a legal challenge from co-founder Huda Ammori.

In a decision published on Thursday, Lord Sales, Lord Leggatt and Lady Simler granted permission for her to appeal to the UK's highest court.

Court records show the case is to be expedited with a hearing expected between October and December.

Following the decision, Ms Ammori referenced the arrests, saying: "This further evidences our case that the proscription of Palestine Action has become a vehicle for a far broader crackdown on expressions of solidarity with the Palestinian people.

"This unprecedented attack on free speech and the right to protest in this country is already having a chilling effect at a time when speaking out about Israel's crimes could not be more urgent."

Hundreds had gathered outside the magistrates' court, where more than 2,000 cases related to supporting the group were due to be heard on Thursday.

But the cases were earlier this week adjourned to October.

Court officials confirmed that all cases relating to Palestine Action have been adjourned to await the outcome of the Supreme Court appeal.

Defendants who had travelled from Yorkshire, Wales and Merseyside told officials they had not been told the hearing was not taking place, complaining of "chaos".

Claire Jeffrey, 52, who travelled to the court from Edinburgh claiming she had not been told her hearing had been adjourned, said: "Scotland's a long way. It's expensive to come here, and we have to rearrange commitments.

"It's just really frustrating to… be told you're on a court roll, and then you turn up, and they're like, 'No, you're not'.

"So it's really discombobulating and frustrating."

Sky News has learnt that the Department for Transport (DfT) will say that new commercial contracts have been agreed with two consortia which between them account for more than 100km of the HS2 route between London and Birmingham.

The two groups are EKFB, which is a joint venture involving Eiffage, Kier, Ferrovial Construction and BAM Nuttall; and Align, which comprises Bouygues Travaux Publics, Sir Robert McAlpine, and VolkerFitzpatrick.

Sources said on Thursday evening that the renegotiated deals were expected to save hundreds of millions of pounds by removing incentives to contractors to escalate spending on the project.

The latest statement from the DfT will come just over a year after Heidi Alexander, the transport secretary, lambasted a "litany of failure" which had left taxpayers facing the prospect of a new rail link costing more than £100bn and fully opening up to 13 years late.

Ms Alexander drafted in a new chairman of HS2 a year ago, with a recent National Audit Office (NAO) report suggesting that ministers were finally making progress on the project after years of controversy.

The NAO estimated that resetting civil engineering contracts could ultimately save the taxpayer as much as £2bn.

Mark Wild, the current HS2 chief executive, recommended an overhaul of the contracting model when he was drafted in last year, the DfT has previously said.

"This is the latest in the series of moves from this government to get HS2 back on track," said a Whitehall source.

"Previous Conservative governments totally lost control of the project, which became a symbol of Britain's inability to get things done.

"The transport secretary has drawn a line in the sand, and this government is clear it will get this railway built as soon as possible, at the lowest reasonable cost, while protecting taxpayers' money."

Ministers have said they now believe the programme, on which more than £45bn has been spent so far, can be delivered in line with a £93.2bn target outlined in May.

HS2 has been beset by disasters over the size and speed of its rolling stock, environmental mishaps and the cancellation of the line beyond Birmingham.

The project currently employs more than 30,000 people.

In a statement issued following an enquiry by Sky News, Mr Wild said: "Bringing an end to HS2's cost over-runs and delays is a shared ambition, and I'd like to thank every one of the parent companies at both EKFB and Align for their willingness to negotiate and their commitment to doing the right thing for British taxpayers."

"Investing in world-class infrastructure is vital to securing economic growth, but it cannot come at any cost."

He added that the news of the renegotiated contracts "represents a significant step forward in our mission to regain control of HS2."    

Talks about renegotiating deals with two other civil engineering joint ventures, one of which includes the London-listed company Balfour Beatty, are understood to be ongoing.

Met Police officers stopped the vehicle in Catford on Wednesday at around 6.30pm and seized £35,000 after searching the vehicle and driver.

The driver was arrested on suspicion of possessing criminal property, and remains in custody.

Further searches at an address linked to him led to officers finding £4million in cash concealed in bags across two bedrooms.

Officers also found 1kg of class A drugs, namely cocaine.

Commander Paul Brogden said: "This is one of the largest cash seizures we've seen and shows the impact that proactive local policing can have in tackling serious and organised crime.

"The arrest highlights the vital role stop and search, including stopping suspect vehicles, can play in helping officers to identify criminal activity.

"This result is testament to the persistence and dedication of the officers involved.

"We'll continue to work relentlessly to disrupt and target those who seek to profit from illegal drugs and cause harm in our communities."

Colin Gray's sentencing comes days after his son, Colt Gray, 16, was sentenced to life in prison without the possibility of parole for the shooting at Apalachee High School, 45 miles northeast of Atlanta.

Two students and two teachers were killed in the incident in September 2024.

A defence attorney for Colin Gray asked the judge for a sentence that would amount to 10 years in prison, followed by 10 years on probation.

But the district attorney said Gray, 55, deserved a sentence of 80 years in prison.

Judge Nicholas Primm noted that all of Gray's crimes were crimes of negligence "tethered to the tragedy committed by his son".

"My heart aches for everyone that was there that day, for all of you that have been impacted by it. But the law requires that I set aside emotion. I don't get to sentence with passion. I have the nearly impossible task of sentencing you without passion despite the immeasurable heartache that you caused," Judge Primm said.

Colin Gray is one of only a handful of American parents who have been criminally charged after their children were accused in shootings, an emerging legal strategy employed by prosecutors in ​a bid to tackle the epidemic of gun violence in US schools.

A jury in March found Colin Gray guilty of second-degree murder in the deaths of two 14-year-old students, Mason Schermerhorn and Christian Angulo.

Georgia law defines second-degree murder as causing the death of a child by committing the crime of cruelty to children.

Colin Gray was also found guilty of involuntary manslaughter in the killings of teachers Richard Aspinwall, 39, and Cristina Irimie, 53.

Another teacher and eight other students were wounded, seven of them hit by gunfire.

Family members of those who died and victims of the shooting condemned what they described as Gray's failures as a parent and urged the judge to hand him the maximum sentence possible.

"He did not pull the trigger but purchased and left a firearm accessible to a minor," said Shayna Aspinwall, whose husband was killed.

She said the sentence must factor in "the families left behind who must carry the grief and trauma for the rest of our lives".

Colin Gray gave his son the rifle as a Christmas present, along with ammunition, a gun sight and other shooting accessories, prosecutors said.

Colt Gray carried the semiautomatic rifle on to the school bus with the barrel sticking out and wrapped in poster board, according to testimony from Barrow County Sheriff's Office investigator Jason Smith.

The teenager left class and went to the bathroom. He emerged with the rifle and shot people in the hallway and a classroom, the investigator said.

Colt Gray, who was 14 at the time of the shooting, had shown signs of deteriorating mental health in the weeks leading up to the incident, according to testimony during his sentencing hearing.

He was part of an online "true crime community", where he and other young people discussed their obsession with mass shooters, an investigator testified.

His mother, Marcee Gray, who was separated from Colin Gray, told investigators she had argued with her estranged husband weeks before the shooting, asking him to secure his guns and restrict their son's access.

Barrow County District attorney Brad Smith rejected the claim made by Colin Gray's attorney that he had little warning of ⁠his son's ​violent plans.

He showed the judge a replica of a bedroom ​wall on which the teenager had made a shrine to the gunman behind the 2018 mass shooting at a high school in ​Parkland, Florida.

The risk was "staring him in the face every day," Smith told the judge.

Not simply because she served before Brexit had fully reshaped Britain's place in the world or before Trump returned to the White House, but because she came of age politically at a time when the foundations of Western foreign policy felt more settled. NATO was rarely questioned.

America's leadership of the alliance was largely taken for granted. International institutions still carried authority. Today's world feels markedly different.

There are few British prime ministers who have looked Vladimir Putin in the eye quite as she has.

The Salisbury poisonings transformed Britain's relationship with Russia overnight, forcing May to confront the Kremlin at one of the most dangerous moments in recent history.

She also spent years working alongside President Trump during his first term in the White House. Few leaders have witnessed so many of the events that continue to shape today's geopolitical landscape.

As I sat opposite her this week, I wanted to know whether those experiences had changed the way she sees Russia, America and the future of the Western alliance - or whether they had simply confirmed what she believed all along.

If anything, they had.

I asked whether another Salisbury-style attack today would provoke the same united response from Britain's allies.

There was no hesitation.

While she acknowledged there were moments when Moscow may have sensed divisions beginning to emerge within the West, Russia's full-scale invasion of Ukraine changed that calculation. If Putin believed democracies lacked the resolve to stand together, she argued, 2022 proved otherwise.

Unsurprisingly, Ukraine dominated much of our conversation. Given President Trump's often unpredictable approach to Kyiv, I asked whether she believed Ukraine could still rely on the United States.

Her answer wasn't really about Donald Trump. It was about Europe.

For years, Trump has argued that European nations should shoulder more of the burden for their own defence. On that point, May believes he has been remarkably consistent. Her message to Europe was unmistakable: the continent can no longer assume the United States will always carry the burden of its security.

The moment that stayed with me, though, came when I asked what advice she would give today's leaders dealing with Putin.

She smiled briefly before replying. "Once a KGB man, always a KGB man."

It was classic Theresa May. Just a sentence that distilled years of dealing with Putin - and a reminder that, in her mind, Russia's strategic ambitions have not changed, even if the world around it has.

I also wanted to know how she believes this war ends. Negotiations, she said, will almost certainly come. But they cannot come at the price of rewarding Russian aggression. Russia cannot be allowed to emerge victorious.

For May, the question is larger than Ukraine itself. It is whether countries can still rely on collective security and whether borders can once again be changed by force without consequence.

If Ukraine dominated the first half of our conversation, Iran shaped the second.

What struck me was her empathy for ordinary Iranians - people she said simply want the opportunity to live peacefully in a democratic country.

At the same time, she warned of Tehran's increasingly close relationship with Moscow and stressed the strategic importance of keeping the Strait of Hormuz open, a reminder of how quickly instability in one region can reverberate across the global economy.

Our conversation ended with Gaza. May reaffirmed her long-held belief that a two-state solution remains the only credible path forward, despite how distant that prospect now appears. It feels more elusive than ever, I suggested. She didn't disagree. But neither had she abandoned hope.

Politics, she reminded me, is ultimately about choices. With sufficient political will, even today's seemingly intractable conflicts can still be resolved.

As we wrapped up the interview, I found myself returning to the question I'd asked at the very beginning. Is May a politician from a different era?

Perhaps.

But after an hour with her, I found myself thinking that consistency - so often dismissed as caution in politics - can also be a form of leadership.

May belongs to a generation of leaders who largely shared the same assumptions about alliances, diplomacy and the role of the West in the world.

Today, many of those assumptions are being tested, not only by Russia and China but increasingly from within the alliance itself. Whether discussing Putin, Trump, Iran or Gaza, her worldview never shifted.

Democracies, she believes, are strongest when they work together. In an age of disruption and uncertainty, that conviction feels less like nostalgia and more like a challenge to the leaders who have followed her.
