As all eyes at Westminster turn to the imminent coronation of Andy Burnham as Labour leader, OppositionCast, appropriately, looks across the chamber to the opposition party and looks at the history of Conservative leadership elections.

Nigel speaks to Lee David Evans, John Ramsden Fellow at the Mile End Institute, about his new book "Coronations and Defenestrations: Choosing (and losing) Tory leaders", which charts an often brutal history of leadership contests. We discuss the effect of different rule changes over the years, and consider the proper definition of a "stalking horse."
