Environmental protesters have ruined King Charles' wax figure at Madame Tussauds in London.

A video of the incident shows at least two protesters affiliated with the British environmental coalition "Just Stop Oil" smashing the figure with a cake as a museum staff member tries to stop them.

In the video, a man and a woman come up to the royal display and take off their black outwear to reveal their "Just Stop Oil" undershirts. The woman then defaces King Charles' wax figure by smashing a frosted cake into its face, as the man follows suit. They then shout their message of protest, calling for an end to new oil and gas agreements.

"The science is clear. The demand is simple: Just stop new oil and gas. It's a piece of cake," the male activist says as a woman from the audience, who appears to be a member of the museum's staff, urges the two activists to stop.

In a statement on Monday, Madame Tussauds announced that the exhibit was temporarily halted following the incident. The popular museum also addressed the destruction of King Charles' wax figure and confirmed that security had intervened to stop the activists.

"At approximately 10:50 a.m. today (Oct. 24) protesters entered the 'World Stage' Zone at Madame Tussauds London and appeared to throw what is believed to be cake at our figures of The Royal Family," said museum officials. "Our security team dealt with the incident quickly and we are working closely with the Metropolitan Police on this matter."

"The attraction remains open, with our Royal Family set closed temporarily," they added.

The wax figure of King Charles depicts the new monarch in a tux, standing next to the wax figure of Queen Consort Camilla, who dons a blue gown. The Royal Family set also features the wax figures of Prince William and Kate Middleton in their evening attires.

Meanwhile, the Metropolitan Police said four people have been arrested for the damage done to the wax figure. The incident is the latest in a string of actions taken by the Just Stop Oil coalition across Europe. Earlier this month, the same group of protesters sprayed orange paint on the Harrods showroom in central London.
