A series of daring, defaced paintings depicting the UKs four most recent prime ministers, created by the New York-based collective The Bruce High Quality Foundation, reflect our turbulent post-truth times. The works, which are on show at the Pippy Houldsworth Gallery in London (5 Years at Heddon Street; until 4 February), show Theresa May and David Cameron with their faces daubed with angry splashes of paint. But what is the reason for this bile-fuelled display? Angry constituents and smart-ass children have been blotting out the faces of their leaders since the beginning of time. As a collective, and therefore our own body politic, we are enacting the will of the people, the artists told i-D magazine.
