Regular listeners will recognise the name - John Tusa has previously appeared on our podcast, talking about his book 'On Board' - a rich insight into the Boards of many public institutions. At the time, we didn't get a chance to talk about his role in the BBC World Service. 

However, a chance comment from a colleague, concerning the famous 'Tusa-grams' sent us right back to John, with a plea to talk more about his role leading the World Service, and how he curated the organisation during a time of significant change. We also got a chance to hear about his latest book - Bright Sparks, which features seven stories of innovation, bravery, tenacity and audacity. Pop on a pair of headphones and be ready to sit back and listen to John sharing some of those stories. The book is out soon. We advise you pre-order it.
