Newsnight - Season 2011 Episode 61 29/03/2011

Strikes on Libya will continue until Col Gaddafi meets UN terms, stops attacking civilians and pulls back his forces, the US's Hillary Clinton has told the London conference of allied leaders. Tonight we'll talk to the Foreign Secretary William Hague. The London conference was intended to be a demonstration of unity but just how solid in reality is the coalition? Our Diplomatic Editor Mark Urban will bring us up to date with the day's events while out in Libya Tim Whewell will bring us a report from Derna, a town in the east from where more fighters went to join al-Qaeda in Iraq than anywhere else in the world. It highlights how little we know about the rebels and what could replace the Gaddafi regime. And our Science Editor Susan Watts will report on the latest CJD scare. Two separate incidents have emerged in which patients have been told they were put at risk of contracting the brain wasting disease - 38 patients have been warned in Wales and 21 in Essex. In both cases the fatal disease could have been picked up during surgery. Susan speaks to one of the patients affected and medical experts about the risk of contracting CJD from surgical instruments.
