Overview: A draft United Nations Security Council resolution is to be put to a vote in New York tonight. If adopted it would authorise a no-fly zone over Libya and allow Arab states and others in co-operation with the UN to protect Libyan civilians, including in the rebel-held city of Benghazi. We will have the result of that vote and be getting reaction from a close Clinton ally in the US. Susan Watts will be reporting on efforts to deal with the crisis at the tsunami-hit Fukushima Daiichi nuclear plant in Japan, assessing what is happening on the ground and also what measures are being taken around the world. And with the events in Japan causing countries to reassess the safety of their own nuclear energy programmes, David Grossman looks at what this means for the prospects of an energy gap in Britain as we aim to meet electricity demands while also meeting deadlines to cut carbon emissions. Plus, remember Citizen Smith? Well he's back - not in the form of Robert Lindsay this time, but our correspondent Stephen Smith. Stephen has been to Big Society boot camp, undergoing training as a Big Society organiser ahead of the government's planned roll out this summer.
