Kofi Annan has been at the centre of the major geopolitical events of our time and with over 40 years of service to the United Nations - the last 10 as Secretary-General - he offers a unique perspective on international diplomacy.

In his new book 'Interventions: A Life in War and Peace' he gives his personal views on the conflicts that have dominated recent history, from the crises in Kosovo and Lebanon to military intervention in Iraq and Afghanistan.

Kofi Annan discusses his life and work before taking questions from the audience.
