I have been a journalist for more than 40 years, and have lived in, worked in, or travelled in, more than 80 countries. I worked for the BBC for more than 20 years and have broadcast from most of the world’s hot spots — Kabul, Baghdad, Kosovo, Harare, etc. — and specialise in world affairs. I’ve also interviewed several world leaders, including Nelson Mandela, Kofi Annan and Tony Blair. In 2013, I received the Charles Wheeler award for outstanding contribution to broadcast journalism.
