A retired electrician who worked for Pablo Picasso has come forward with a cache of 271 of previously unknown works by the artist, worth an estimated $80 million. Pierre Le Guennec, 71, says Picasso gave him a box containing the works as a gift, but France’s art police have already raided Mr Le Guennec’s home on the Cote d’Azur, confiscated the works, and a long legal battle will now begin.
