Sandi Toksvig hears about a lost Emperor of India: Ashoka ruled the subcontinent about 2,200 years ago and left many pillars and rocks carved with his edicts. Historian Charles Allen went in search of the legacy of this once great Emperor a journey which took him to some of the remoter parts of the country. Writer Tim Moore and webmistress Cathy Shaw both have an interest in visiting some of the least attractive sounding places in Britain and have made many trips to find out if the reputations of towns like Middlesbrough and Scunthorpe for being undesirable destinations are justified. Producer: Harry Parker.
