Supporters of Just Stop Oil have covered a Madame Tussauds waxwork model of King Charles III with chocolate cake.
Just Stop Oil say two protesters bought tickets to Madame Tussauds at just after 10.30am before stepping over the rope barrier separating the waxwork of the King from the public.
The pair wore white t-shirts during the protest, with the wording "Just Stop Oil" printed on them.

In a post on their Twitter account, Just Stop Oil said: "Two supporters of Just Stop Oil have covered a Madame Tussauds waxwork model of King Charles III with chocolate cake, demanding that the Government halts all new oil and gas licences and consents."
Four people have since been arrested for the incident, the Metropolitan Police have confirmed.
They said: “We responded quickly to an incident at Madame Tussauds after two people threw food at a statue at approximately 10.50am.
“Four people have been arrested for criminal damage related to this incident.”
The protest is the latest in a string of action carried out by the group.
Four Just Stop Oil protesters have been arrested for “wilful obstruction” after blocking traffic on London’s Abbey Road on Sunday.
The climate activists blocked traffic on both carriageways of the North London crossing made famous by The Beatles.
The protesters recreated the pose from the cover of The Beatles’ Abbey Road album at the crossing.
They then unfurled a poster with the slogan ‘Just Stop Oil’, before blocking traffic by sitting in the middle of the road.
A statement from the Metropolitan Police said: “Both carriageways of Abbey Road are now clear of protesters and traffic is flowing again in both directions.
“Police have arrested four protesters for wilful obstruction of the highway.”
