IRAN

We've an exclusive report on the arrests in Iraq of individuals believed to be connected to Iranian intelligence. Newsnight has been told that the Iranians were not directly involved in weapons shipments or in fomenting terrorism - but in something potentially even more extraordinary: they have been using their influence to direct policy in Baghdad. We'll be exploring how far this further damages the credibility of the already embattled Prime Minister Nuri al Maliki, and whether it might also be used next week by George Bush to justify a "surge" of new US troops in Iraq.

FOOD LABELLING

Should it be a simple traffic light system - green, amber and red -- or something more detailed as some big food companies want? And does having two rival systems make it any easier for the consumer to make choices about the content of their food. Advocates for both labelling systems go head to head.

NHS

As we reported last night a leaked report suggests the numbers of consultants and nurses predicted to be in the NHS in the next few years does not match the numbers we will actually need. Whose fault is this? And is it simply impossible for anyone, however talented, to plan the future of a bureaucracy as big as the NHS.

SIERRA LEONE

Following our interview with Oprah Winfrey last night on her personal aid for Africa, we've a special report from Sierra Leone, where five years after the civil war, the country is facing a health crisis. An estimated 40% of the population is traumatised but there is just one trained psychiatrist in the entire country.
