Julia Hartley-Brewer examines the role of Leader of the Opposition and asks what lessons David Cameron can learn from history as he plots his path to power. He has already abandoned his party's confrontational stance as he bids to recast the image of the Tories as the nasty party and rebrand it as modern, compassionate and caring. The programme looks at what he can learn from the tactics of previous opposition leaders, from Winston Churchill to Tony Blair.
