Leonardo Da Vinci fresco 'found' claim

A lost masterpiece by Leonardo Da Vinci may have been found hidden behind another work of art on a wall in Florence.

An art historian leading the hunt for the fresco says he has discovered traces of paint that were only used by the artist.

But some have dismissed the search as a publicity stunt, as David Sillito reports.
