The focus of the programme will be the Libya conflict. Events are moving fast following last night's UN Security Council resolution authorising all necessary measures to protect civilians from attacks by Colonel Muammar Gaddafi's forces.
In the face of Western powers discussing how to enforce the no-fly zone, Libya's government has declared an immediate ceasefire, with Foreign Minister Mussa Kussa saying that it was intended "to protect civilians".
Tonight, Mark Urban will be bringing us up to date on the latest military plans, Michael Crick will be giving us political analysis of David Cameron's role in pushing for action and we will be discussing the crisis with guests in the studio.
