Cameron says he regrets that EU countries announced
separate policies to deal with the financial crisis 
David Cameron is the leader of the UK's opposition Conservative party.

In a week when much of the focus of the credit crisis has been on Britain, Sir David asks Cameron just how worried he is about it.

Cameron discusses both his support for the government's bank bailout plan and the root causes of the current financial crisis, including what he calls the "toxic debt" of the sub-prime mortgage crisis in the US and the UK's "debt-fueled boom".

The opposition leader also considers how the EU has handled one of its toughest challenges yet before going on to talk about the Russia/Georgia conflict and the West's failure to send a sufficiently strong message to Russia and the need to place a greater emphasis on the political process in Afghanistan.

Jaime Bermudez

Bermudez discusses the controversy surrounding Ingrid Betancourt's rescue
After more than 40 years of fighting the Farc, the Colombian government seems to be making a breakthrough.

Earlier this year, after a raid that killed a senior rebel leader, the government seized computers that contained not only files that linked Venezuelan and Ecuadorean governments with the Farc, but also the names of over 9,000 rebels.

Just a few months later Ingrid Betancourt, a former presidential candidate and high-profile hostage, was rescued.

Sir David talks to Jaime Bermudez, the Colombian minister of foreign affairs, who says that while there is still more to be done, crime rates - including murder and kidnapping - are down and tourism is on the up.

Shane Warne

The Australian cricketer shows Sir David his bowling techniques
A legend of cricketing history, the Australian sportsman is widely regarded as one of the finest leg spin bowlers of all time.

He talks to Sir David about some of the world's greatest cricketers - many of whom he played either against or alongside in the course of his extraordinary career - and reveals who makes it to the top of his list.

Warne also presents the case for Twenty20 cricket, arguing that it is good for the brand of cricket and introduces the game to a whole new group of spectators.

Zbigniew Brzezinski

The foreign policy expert explains why he is supporting Obama's bid for the White House
Zbigniew Brzezinski is one of the most respected figures in the field of foreign policy. He served as national security advisor to Jimmy Carter when he was US president and explains why he is supporting Barack Obama, the Democratic presidential candidate, in his race for the White House.

Brzezinski shares his views on how US foreign policy must change in the future and the claims that Obama is too inexperienced to be the next US president.

He tells Sir David that it is "a sense of a person's ability to relate to the dilemmas and challenges of the new age that is important".

Brzezinski goes on: "I sense that Obama understands what is essentially new about the 21st century. I am convinced, unfortunately, that McCain is rooted entirely in the preceding century."
