Andrew Marr talks to Niall Ferguson about the history of civilisation, and how the West came to triumph over what appeared to be superior empires in the East, and whether that ascendancy is in permanent decline. While the economist George Magnus questions whether emerging markets, like China, really are about to dominate the world. The Queen will celebrate her Diamond Jubilee next year, and the commentator Peter Whittle presents a robust defence of the monarchy as one of Britain's leading institutions. And as revolution and change sweep across the Middle East, Professor Madawi Al-Rasheed looks at the impact on the Kingdom of Saudi Arabia.
