British pop art pioneer Richard Hamilton, whose work ranged from images of consumer culture to parodies of political leaders, died yesterday at the age of 89, the gallery that represented him said.

The artist won worldwide recognition for designing the cover of the Beatles’ White Album and in recent years for his depiction of then British prime minister Tony Blair dressed as a cowboy.

The Gagosian Gallery, a chain of galleries which represented Hamilton and had branches in several countries, said the art world had “lost one of its leading figures”.
