Tom Fletcher, former British Ambassador to Lebanon and known as the 'naked diplomat' for his direct, unvarnished approach, argues that the future of diplomacy will be citizen-led.

Speaking at the Hay Festival, the 'ex-Excellency' explains how in the digital age most people doing diplomacy - what he describes as a basic human reflex to find common ground - will never have crossed the threshold of a Foreign Ministry. Instead, they will be working for NGOs, the media, in business, elsewhere in government or in communities.
