Tim Whewell talks to General Suleiman Mahmoud of the Libyan rebel forces who tells him the rebels need weapons if they are to overthrow Colonel Gaddafi. He says with arms they could do the job in two weeks, but without it could take six months. The US President Barack Obama has said he does not rule out arming the rebels as government forces push them back.

We'll also be taking a close look at the arts and sciences. Which brings the most economic benefits to our society? We will have a film putting the case for each and a discussion with guests including Deborah Aydon, Executive Director of the Liverpool Everyman and Playhouse theatres and Imran Khan, Director of the Campaign for Science and Engineering in the UK And Ed Miliband is to marry in May. Why has he decided to tie the knot now ? And why will there be no best man (i.e. David) at his wedding?
