Why is it so hard to pin down what we mean by it? The Greeks called it a gift of grace, but it’s been widely interpreted ever since. Why do we disagree so strongly about who has it? And are its traits inherent or can they be learnt?

The programme explores the magnetic appeal of politicians, sports stars and religious leaders. And asks whether it’s possible for people to 'learn' charisma.
