John Cooper Clarke, poetry's Punk Laureate, nominates Salvador Dali, the surrealist behind melting clocks, lobster telephones, and that trademark moustache.

Matthew Paris asks whether Dali was a genius artist or just a gifted marketeer of his own brand image, who latterly embraced commercialism.

"Both" comes the resounding answer from his champion John Cooper Clarke and the art historian Professor Dawn Ades, who recalls meeting the artist when just she just rang his doorbell in Figueres, Catalonia, back in 1968.
