Co-leader of the Green Party, Jonathan Bartley, has been arrested for taking part in the Extinction Rebellion climate change protest at Whitehall.
As he joined demonstrators in blocking the road near Westminster, Mr Bartley said: “We cannot go on with HS2 destroying acres and acres of countryside.
"We cannot go on with subsidising fossil fuels, we cannot go on with our road building programme, we cannot go on even with our nuclear programmes."
He was cut off by police who lifted him from the ground and arrested him for obstructing the highway.
The Green Party co-leader was arrested today
The co-leader, who is celebrating his birthday today, was praised by his party counterpart Sian Berry for “standing up for peaceful protest”.
She wrote on Twitter: “On his birthday too - @jon_bartley standing up for our right to peaceful protest.
“In a democracy this is the very definition of not a crime. Proud of my @TheGreenParty co-leader and those he was arrested alongside today.”
One of those detained alongside the politician was journalist George Monbiot, who had written in a column this morning that he “hoped to get arrested”.
WATCH: The moment George Monbiot was carried away by police
The 56-year-old climate activist refused to move from the road at Whitehall while Extinction Rebellion supporters lay down next to him to prevent officers from carrying him away.
Three were arrested but were replaced by others, while surrounding activists played the drums and chanted “power to the people”.
More than 1,600 people have been arrested in connection with the “Autumn uprising” protests since they began on October 7.
The Metropolitan Police has since imposed a ban on the demonstrations, which they said have become “unlawful” due to the blocking of major roads and the continued serious disruption.
