Just Stop Oil protesters have descended on Whitehall and were seen obstructing traffic near Downing Street and around the Cenotaph.
A mother-of-one lying cuffed on the base of the war memorial said: “They arrested us in the road and we were dragged to the pavement and then back over here.”
One officer said the protesters had been moved to the site “to get them off the road”, adding: “It was for their own safety, obviously it’s quite a busy road.”
The Met said they arrested at least 40 activists who were slow-marching in Whitehall under Section 7 of the Public Order Act.
The campaign group said in a social media post that 100 JSO supporters had taken to the street in central London to protest against oil and gas deals.
In a statement on the group’s website, it said: “At 11:33am this morning, 130 Just Stop Oil supporters from the North and South West of England began marching down Whitehall from Trafalgar Square.
“A small number of Metropolitan Police arrived at 11:37am. At 11:52 am they began arresting Just Stop Oil supporters for allegedly breaching Section 7 of the Public Order Act 2023, but they were unable to bring the march to a halt at this stage, and the supporters made their way to Parliament.”
The group claimed that by 12.13pm, “all Just Stop Oil supporters were arrested, with most peaceully refusing to comply with the police”.
This comes shortly after two activists were arrested on Monday morning for smashing the glass protecting a painting at the National Gallery.
The Met Police confirmed that two people had been arrested on suspicion of causing criminal damage after the glass around the Rokeby Venus, painted by Diego Velazquez, was smashed with safety hammers.
