Logo for HARDtalk - Christine Lagarde - French Finance Minister

In the run up to London's much hyped G20 summit, HARDtalk is in Paris talking to France's Finance Minister, Christine Lagarde. On the key issues facing the G20 - from the need for more fiscal stimulus, to the role of economic nationalism, and the scope for further regulation - Nicholas Sarkozy's France has at times seemed out of sync with Barack Obama's America. But just how real are those differences? Christine Lagarde talks to Stephen Sackur.
