King Charles’ first official portrait has been vandalized by animal rights activists.

The 75-year-old monarch unveiled the work by artist Jonathan Yeo in May but on Tuesday activists from Animal Rising entered the Philip Mould Gallery in London and pasted a picture of the claymation character Wallace of ‘Wallace and Gromit’ onto his face.

In a nod to the fictional inventor, a speech bubble was also pasted on, which read: “No cheese Gromit. Look at all this cruelty on RSPCA farms.”
