A new exhibition at London's National Gallery hopes to shed light on artists in 14th Century Siena, who have often been overshadowed by their Tuscan neighbours in Florence. Samira is joined in the studio by one of the curators, Imogen Tedbury, and by Maya Corry, a Renaissance expert from Oxford Brookes University to discuss the astonishing colours and use of gold by artists like Duccio, the Lorenzetti brothers and Simone Martini.

The death has been announced of Bill Dare, the creator of Radio 4's The Now Show and Dead Ringers.
