Juan Manuel Santos, the former Colombian defence minister, will be Colombia's next president after he won a thumping victory in Sunday's presidential run-off against ex-Bogota mayor Antanas Mockus.
The conservative Santos says he will continue the policies of Alvaro Uribe, the popular outgoing president.
But Uribe leaves the new leader of Colombia with a host of major problems including a decades-old leftist rebellion, the highest unemployment in Latin America, and strained relations with neighbours Venezuela and Ecuador.
On Monday's Riz Khan we ask: How will Santos deal with these critical problems?
Discussing those issues will be María Victoria Llorente, the executive director of Fundación Ideas Para la Paz which is a Bogota-based peace-building initiative that seeks to end armed conflict through information, monitoring and research.
We will also have with us Larry Birns, the director of the Council on Hemispheric Affairs which is a Washington, DC-based non-profit organisation that promotes common interests in the western hemisphere.
This episode of the Riz Khan show aired from Monday, June 21, 2010.
