We have a live interview with MP Eric Joyce, who was forced to resign from the Labour Party and apologise to victims after being convicted of assault over a bar brawl in Parliament.

And we have the latest on the A4e story.

We have obtained the results of a confidential 2009 internal audit of work by A4e's top recruiters in which auditors found examples of staff claiming for putting people into jobs which did not exist, jobs which did not qualify for payment and fabricating paperwork to back up claims. Read more about it here.

Tim Whewell is in Toulouse where police shot and killed the gunman who carried out a spate of murders, but where questions are now being asked about how a known radical returning from al-Qaeda-controlled areas of Afghanistan and Pakistan was able to stockpile weapons and carry out the attacks with the intelligence services having little or no idea of his whereabouts.

Also an independent review into police pay and recruitment commissioned by Home Secretary Theresa May has recommended that police officers' fitness be checked annually with disciplinary procedures facing any officer who fails the test three times.

Is this a good plan, or is there more to being a good police officer in the 21st Century than being able to chase down a criminal on foot?

As the deadline for Greek debt swaps passes, Paul Mason looks at whether a disorderly default is on the cards.

Also, President Barack Obama and Israeli PM Benjamin Netanyahu are meeting in the US, with Iran's nuclear ambition lurking in the diplomatic shadows.

The Health and Social Care Bill has completed its Commons stages but is having a difficult passage through the House of Lords, which has tabled a number of amendments, and is being opposed by many groups representing medical professionals.

If passed, the bill would give GPs control of much of the NHS budget and opens up the health service to greater competition from the private and voluntary sector.

Our Political editor Allegra Stratton will be joining Health Secretary Andrew Lansley at a 'listening event', where he will be putting his proposals to the professionals involved. Mr Lansley will also be interviewed by Jeremy.

In the studio, health minister Simon Burns will be joined by a number of medical professionals to discuss the measures and the impact on the health system.
