Andrew Marr looks at what the future holds for Ireland after the financial crisis, with the cultural commentator, Fintan O'Toole, who argues for wholesale reform of the political system. While the Conservative MP, Nick Boles puts forward his blueprint for a new Britain. The fate of Deborah Cadbury's family firm was sealed when it was bought out by an American company. But she looks back at a chocolate dynasty that mixed sweet success with bitter rivalry. And the cellist Steven Isserlis is on a mission to enhance the reputation of the much-maligned composer, Saint-Saens.
