Kingsley, a former Lieutenant Colonel in the British Army, now works in the area of conflict resolution with the Causeway Institute for Peace-building and Conflict Resolution International. He has teamed up with Professor Paul Cornish to assess what the future might look like from a security perspective in 2020: World of War. He is not someone who shies away from controversy and spirited debate. He will be returning to Kells after a feisty contribution to our Brexit discussion in 2016, which emerged organically after the result of the referendum vote was announced on 24 June. Kingsley talks to Myles Dungan.
