Ian Hargreaves has over 30 years’ experience as a journalist. He’s been Director of BBC News and Current Affairs, and Editor of the Independent and The New Statesman. He was also a former Director of Cardiff’s Centre for Journalism Studies and Director of Greenpeace UK.

There’s only one currency that works with journalists, and funnily enough it’s neither drink nor money. It’s ideas that get into newspapers, magazines or radio shows.
