Just Stop Oil’s attacks on art risk becoming a cliché | Claire Armitstead

Though there is situationist wit in throwing soup over Van Gogh's Sunflowers, the protest is more likely to provoke eye-rolls than action

If you're going to make a political statement by attacking an artwork then pick a big one. In the absence of the Mona Lisa, Just Stop Oil protesters today threw soup over one of the 19th century's most recognisable images - immortalised on biscuit tins and tea towels the world over - Van Gogh's Sunflowers. The National Gallery attack is the latest in a campaign that saw them glueing themselves to a reproduction of Leonardo da Vinci's painting The Last Supper in the Royal Academy in July.

Such assaults are now so common that the Mona Lisa - most recently pelted with cake at the Louvre in Paris back in May - now smiles on from behind a pane of bullet-proof glass. The sunflowers themselves are unlikely to have suffered any damage, beyond the indignity of being eclipsed by a brighter shade of orange. The protesters will have known this, and there is a certain situationist wit in their choice of weapon - not a spray can but a tin of tomato soup, as immortalised by Andy Warhol, in the pop artist's critique of exactly the sort of industrialisation that Just Stop Oil sees as responsible for the destruction of the planet.
