The former FT editor’s new diaries – The Powerful and the Damned: private diaries in turbulent times – provide a fascinating insight into the high finance and politics of the last 15 years. Published this week, they take in encounters with Presidents, Prime Ministers and CEOs, spanning the global financial crisis, Brexit and much more.

Lionel Barber is in conversation with Reaction editor Iain Martin on Tuesday 10 November from 6pm until 7pm. There will be an opportunity for readers to ask questions.

This is a Reaction event in support of the Reaction Student Programme, training next generation journalists.
