The BBC Insider's Debate - 19/07/2008
A new series of BBC Insiders Debates discusses three topics in depth with those who know most about them.
The Goodwill Ambassadors
At UNESCO headquarters in Paris, Owen Bennett-Jones meets five UNESCO Goodwill Ambassadors - a pop-star, a princess, a space scientist, a global icon and a former prime minister - for a lively and frank discussion about what they do and whether there is any point to their roles.
The participants are musician Jean-Michel Jarre, Princess Firyal of Jordan, scientist Cheick Modibo Diarra, Phan Thi Kim Phuc, who was photographed as a seven-year-old burned by napalm in Vietnam, and the former president of Iceland, Vigdís Finnbogadóttir.
