Animal rights activists have targeted the first official portrait of Britain's King Charles III since he became monarch, pasting a large image of the well-known animated character 'Wallace' over his face, in a protest about welfare on farms.
Footage from campaign group Animal Rising showed two of its supporters approach the portrait in London's Philip Mould gallery on Tuesday, and overlay the King's face with a big cartoon image of Wallace from the Wallace and Gromit animated comedy franchise.
They also pasted a large speech bubble, saying: "No cheese, Gromit. Look at all this cruelty on RSPCA farms!"
The RSPCA wasn't impressed.
"We are shocked by this vandalism of His Majesty King, our Patron’s, portrait. We welcome scrutiny of our work, but we cannot condone illegal activity of any kind," an RSPCA spokesperson said, adding the charity took any allegations about its Assured certified farms seriously.
The attack is the latest by activists on artwork in Britain.
Climate protesters attempted to smash the case holding an original Magna Carta text in the British Library last month, and threw soup over Vincent van Gogh's painting Sunflowers at London's National Gallery in October last year.
He hoped Charles would "seriously reconsider if he wants to be associated with the awful suffering across farms being endorsed by the RSPCA."
Buckingham Palace said it had no comment.
Animal Rising said its posters would be easily removable without causing damage to the painting.
The portrait of Charles, by artist Jonathan Yeo, received a mixed reception after its unveiling last month, with some criticising its vibrant red colour.
