What makes a good leader? Tony Abbott is the latest in a line of Australian Prime Ministers who have struggled to maintain leadership of their party. Abbott may have survived a leadership spill but as the public continues to scrutinise each "captain's call", and politicians from both sides express a lack of confidence in Abbott's leadership, Insight asks – what makes a great leader? A panel of leaders from different fields sits down with host Jenny Brockie to discuss what it takes to be successful in the top job. They explore how much ambition matters, the value of personal loyalty, when to listen to or ignore advice, and whether leading is innate or can be learned. The leaders will also challenge the wisdom of Australia's "tall poppy syndrome" and reveal just how lonely it can be at the top.
