Just Stop Oil is to stop throwing soup on paintings and slow marching in streets as it announces its final protest.

In a statement, the environmental campaign group said: “Just Stop Oil’s initial demand to end new oil and gas is now government policy, making us one of the most successful civil resistance campaigns in recent history.

“We’ve kept over 4.4 billion barrels of oil in the ground, and the courts have ruled new oil and gas licences unlawful.

“So it is the end of soup on Van Goghs, cornstarch on Stonehenge, and slow marching in the streets. But it is not the end of trials, of tagging and surveillance, of fines, probation and years in prison.”

It added: “As corporations and billionaires corrupt political systems across the world, we need a different approach. We are creating a new strategy, to face this reality and to carry our responsibilities at this time. Nothing short of a revolution is going to protect us from the coming storms.”

Just Stop Oil has called for the British government to halt new fossil fuel projects in the UK.

The group’s actions have grabbed headlines – with campaigners having glued themselves to roads and attached themselves to infrastructure at oil facilities.

They have also disrupted sport events and vandalised famous artworks.

Hundreds of the protesters have been arrested and some have been handed lengthy jail terms.

Last week, nine Just Stop Oil protesters were convicted after police intervened to prevent them from gluing themselves to the runways at Heathrow Airport.

Seven of the demonstrators, aged between 26 and 61, were arrested after they were found with glue and angle grinders close to the perimeter fence of the airport in July 2024.

Earlier this month, the group’s co-founder Roger Hallam had his five-year prison sentence reduced by a year after a High Court appeal.

Hallam was jailed last July over a plot to disrupt M25 traffic, which saw 45 people climbing onto gantries over the motorway.

He was among a group of 16 activists who challenged jail terms of between 15 months and five years for their roles in four demonstrations between August and November 2022.

Ten of them had their appeals dismissed.

A man has been arrested on suspicion of murder after a motorist was struck by another driver.

Police said both men were involved in an altercation in Oldham, Greater Manchester.

They were called to reports of a fight in Broadway, Chadderton, close to the Elk Mill roundabout, at about 6.40pm on Wednesday.

A 50-year-old man was pronounced dead at the scene – and a 32-year-old suspect later handed himself into police.

The suspect remains in custody for questioning, Greater Manchester Police said.

A law banning ninja swords is set to come into force by summer after a “relentless” campaign by the family of a murdered teenager.

Ronan Kanda, 16, was stabbed to death with a ninja sword yards away from his home in Wolverhampton in 2022 in a case of mistaken identity.

Now, the final part of Ronan’s Law, a series of anti-knife crime measures, will make it illegal to possess, sell, make, or import ninja swords from 1 August.

The ban will be presented before parliament on Thursday and will come into force in the summer once it has gained approval.

Ronan’s mother, Pooja Kanda, has said: “Today marks a very important day for us as a family and our campaign.

“Since losing our beautiful boy Ronan, we have relentlessly campaigned for a ban on ninja swords – the lethal weapon which took his life.

“We believe ninja swords have no place in our society other than to seriously harm and kill.”

Ms Kanda added: “Each step towards tackling knife crime is a step towards getting justice for our boy Ronan.”

Anyone caught with a ninja sword in private could face six months in prison, set to increase to two years under plans in the Crime and Policing Bill.

The weapons can be handed over in knife surrender bins or local police stations under a surrender scheme running in July.

Under Ronan’s Law, the Home Office has also announced a raft of measures including making retailers report bulk or suspicious sales to police, and increasing the jail sentence for selling weapons to children, or illegal blades such as zombie knives, to two years.

Home Secretary Yvette Cooper said: “We are acting with urgency to bring forward measures to prevent deadly weapons from getting into the wrong hands and will continue to do whatever is needed to prevent young people being killed on our streets as part of our mission to halve knife crime over the next decade.”

Patrick Green, chief executive of Ben Kinsella Trust, also backed the ban, adding: “These weapons, with no practical purpose beyond violence, are simply instruments of war and have absolutely no place in our society or on our streets.”

Two teenagers – Prabjeet Veadhasa and Sukhman Shergill – were sentenced to a total of 34 years in prison for Ronan’s murder.
