Organised crime in the UK - how has it changed? Professor Dick Hobbs, joins Laurie Taylor, to discuss his work on 'Lush Life', a rich, ethnographic study into 'Dogtown', a composite of several overlapping neighbourhoods in East London. Looking behind the clichéd notions of criminal firms and underworlds, he finds that activity which was once the preserve of professional criminals has now been normalised. He invites us to consider whether or not the very idea of organised crime has become outdated in a predatory, post industrial world in which many fight, by illegal as well as legal means, to survive on the margins. Also, the presence and activities of Mafia style crime both in Italy, as well as in the UK. Dr Felia Allum, a Lecturer in Italian History and Politics, discusses how Italian organised crime functions outside its territory of origin. Revised repeat.Producer: Jayne Egerton
