Forces loyal to Libyan leader Colonel Muammar Gaddafi have moved into eastern areas for the first time since towns there fell to protesters two weeks ago, with reports of heavy fighting between them and anti-Gaddafi rebels in the oil town of Brega, 100 miles south of the rebel stronghold of Benghazi. Earlier Col Gaddafi said on TV he would "fight until the last man and woman" and warned that thousands of Libyans would die if Western forces intervened. Tonight, as we will have the latest on the Gaddafi fight back from Lyse Doucet in Benghazi and Tim Whewell will be assessing whether there is any sign of a joined up global response to the crisis. Michael Crick is Barnsley ahead of tomorrow's by-election finding out what matters most to voters there. Also, more than 600 Oxbridge academics are demanding a halt to the £9,000 tuition fee rise, saying they have had no time to work out how it will be implemented. Universities Minister David Willetts and one of those critics will go head to head on the programme tonight.
