This week Sir David talks to Rajiva Wijesinha, Sri Lanka's permanent secretary to the ministry of disaster management and human rights, about the aftermath of the country's 25-year civil war, and to Iranian authors, Azar Nafisi and Hooman Majd, about Iran's relations with the West.
This episode of Frost over the World aired from Friday, September 11, 2009.
After 25 years of fighting and more than 80,000 casualties, Sri Lanka's civil war came to an end four months ago. However, there are still nearly 300,000 displaced people languishing in government-run camps and stories of maltreatment and malnutrition are rife.
But neither the UN nor independent journalists have yet been granted free access to the camps to either confirm or deny the stories.
Rajiva Wijesinha, the permanent secretary to the ministry of disaster management and human rights, discusses this.
A report published earlier this week has said that some European leaders are trying to prevent Turkey gaining full EU membership.
Emma Bonino, a former European commissioner and a vice president of the Italian senate, joins the show to discuss this.
Plus, Sir David asks Iranian authors Azar Nafisi and Hooman Majd what the Iranian people think of their country's nuclear programme and outspoken president.
