Senior diplomats are meeting in Paris for a major international conference on Libya's future. What should that future look like, and will the National Transitional Council and international community's vision dovetail or not? Tonight Peter Marshall will bring us the latest from the Paris conference and Tim Whewell will report from Libya. We have a report from David Shukman on illnesses linked to the dust from the attacks on New York's World Trade Center on 11 September 2001, affecting thousands. Plus we look at government proposals to overhaul planning laws in order to jump-start the building industry and the economy, a major shake-up which green campaigners say will lead to a development free for all and a legacy of blighted landscapes and urban sprawl.
