Overview: Tonight on Newsnight we will be joined live in the studio by UK Chancellor George Osborne and French Finance Minister Christine Lagarde as we focus on the problems at the heart of the Eurozone. Our Economics editor Paul Mason will present his thesis on why EU governments and bureaucracy have mishandled the sovereign debt crisis, imposing unrealistic penalties on the population to save the banks in their own heartlands. And Paul will be giving us his thoughts on what Mr Osborne and Ms Lagarde tell us. We also have an interview with Kate and Gerry McCann, whose daughter disappeared while on a family holiday in Portugal four years ago, about the book Mrs McCann has written on their ordeal and ongoing efforts to locate Madeleine. Then our Science editor Susan Watts has the story of the secret US embassy cables released by Wikileaks which show nations are racing to "carve up" Arctic resources - oil, gas and even rubies - as the ice retreats (read more here). And Iain Watson has the latest on the news that the Lib Dem MP David Laws is to be suspended from the Commons for seven days over his expenses claims, which he used to pay rent to his partner and for building work and telephone bills.
