A number of Greenpeace activists have been arrested after an hours-long protest on the roof of Rishi Sunak's mansion over his new fossil fuel drilling "frenzy".
Four campaigners draped the British Prime Minister's grade II-listed manor house in North Yorkshire with an oil-black fabric to "drive home the dangerous consequences".
Police were "managing the situation" after being called to the family home in Kirby Sigston, near Northallerton, at about 8am after the activists climbed the roof while Mr Sunak, his wife and children were on holiday in California.
The group returned to the ground at about 1.15pm and were being spoken to by officers before being loaded into the back of police vans.
A North Yorkshire Police spokeswoman at the scene confirmed that the four protesters who scaled the roof had been arrested.
Deputy Prime Minister Oliver Dowden, who is standing in for Mr Sunak during his holiday, told the protesters to "stop the stupid stunts".
A former deputy chief constable of North Yorkshire Police said it was a "major breach of security", as he called for an "investigation into how this has been allowed to happen".
Mr Sunak, MP for nearby Richmond, this week announced plans to "max out" the UK's oil and gas reserves by granting more than 100 new licences for extraction in the North Sea.
He also hinted that the UK's largest untapped oil field, Rosebank, to the west of Shetland, could be approved despite fierce opposition from environmental campaigners.
Climate-conscious Conservatives have joined campaigners to warn against the move, amid concerns it will hinder efforts to reach net-zero by 2050.
After scaling the house with ladders, the four activists unfurled the black fabric and brandished a banner demanding "no new oil" as they urged Mr Sunak to "be a climate leader, not a climate arsonist".
Protester Alex Wilson, who lives in Newcastle with her partner, who was also on the roof, released a video message from on the roof of Mr Sunak's house.
"We're all here because Rishi Sunak has opened the door to a new drilling frenzy in the North Sea while large parts of our world are literally on fire. This will be a disaster for the climate," the climber, originally from East Yorkshire, said.
On the ground, Greenpeace UK climate campaigner Philip Evans defended the action at the prime minister's family home.
He told the PA news agency the group had knocked on the door when they arrived and said "this is a peaceful protest", but there was no answer.
Asked whether it was intrusive to target someone's home, Mr Evans said: "This is the prime minister. He is the one that was standing in Scotland going to drill for every last drop of oil while the world is burning.
"He is personally responsible for that decision and we're all going to be paying a high price if he goes through with it. It is personal."
North Yorkshire police said they had been "responding to reports of protest activity".
"Officers have contained the area and no-one has entered the building," a statement added.
Peter Walker, who stepped down as the force's deputy chief constable in 2003, said he was "absolutely astonished" the protesters gained access to the house, as he called for an investigation.
