The House of Commons - an anthropologist's guide to the political 'tribe'. Emma Crewe, Professorial Research Associate at SOAS, spent two years doing interviews in the Palace of Westminster and MPs constituencies. She talks to Laurie Taylor about her study, which provides a fascinating glimpse into the hidden mechanisms of parliamentary democracy. She's joined by Lord Daniel Finkelstein, political commentator and associate editor at The Times.

Also, Anne Phillips, Graham Wallas Professor of Political Science, asks if inequality impacts on rates of voting in general elections.
