The satirical show Spitting Image spanned Margaret Thatcher's government and lasted to the end of John Major's. The puppets themselves became almost as famous as the politicians they represented, and in 2000 were auctioned at Sotheby's. The programme traces where they now reside, and meets the caricaturists, mould-makers, writers, directors and the rest of the team who worked tirelessly to make the series a success.
