In the light of recent revelations about feuding in the Labour party does it make sense to demand or even expect loyalty from people in public life? Two former newspaper editors, Andreas Whittam Smith and David Yelland will be joining Philip Dodd to give their opinions. Also in the programme the historian, Tom Holland, will be sharing his passion for Herodotus; Tim Clark and Rosina Butler will be discussing the evolution of the Japanese erotic print; and the Magnum photographer, Martin Parr will be paying tribute to one of his gurus - the late Tony Ray Jones.
