Debates in Davos

The BBC's Economics Editor Stephanie Flanders presents a special edition of Business Daily from the annual World Economic Forum in the Swiss mountain resort, Davos. She speaks to the Chief Executive of Goldman Sachs Lloyd Blankfein about the morality of tax and discusses the UK Prime Minister's decision to call for a referendum on Britain's membership of the EU. Swedish Finance Minister Anders Borg tells her that Europe's future rests on the future of the banking system. And the BBC's Simon Jack gives his insight into what it's like to be strolling the corridors of power at the World Economic Forum.
