Kirsty Young's castaway is the barrister Michael Mansfield.

He is one of Britain's leading QCs - the Birmingham six, the Marchioness disaster, the Stephen Lawrence trial and the death of Jean Charles de Menezes are only a handful of the high profile cases he's been involved in.

He describes himself as a 'radical lawyer' and says he's been educated by the cases he's taken on. He has become, he says, increasingly angry and radical over the years. "I do feel that reputation, standing up for principle, is one of the few ways in which a difference can be made."
