French satirical magazine Charlie Hebdo has produced a new edition a week after gunmen murdered eight journalists and four others at its offices in Paris. British Muslims have been urged to react with restraint to the magazine's new cartoon depicting the Prophet Muhammad. Four Jewish men also died after an Islamist gunman took hostages at a kosher shop in a separate attack in Paris two days later, and a policewoman was murdered in a third shooting believed to have been carried out by the same attacker.

Let's take a moment to look through the other political stories of the day. Chancellor George Osborne is to deliver a speech to the Royal Economic Society later in which he will seek to calm nerves over the risk of deflation, after a sharp fall in UK inflation to 0.5% in December - its lowest rate since May 2000. Mr Osborne will say this is welcome news, and not a cause for concern. Labour says the benefits of falling energy costs are not being passed on to consumers.

So what can we expect to crop up? Most likely, the question of TV election debates. Ed Miliband, Nick Clegg and Nigel Farage have written to David Cameron warning him that they want the leaders' debates to go ahead even if he refuses to take. Mr Cameron has said he would only appear if the Green Party was included - but the trio of leaders say it would be a set back to the democratic process if the debates did not take place.

Last week's session - the first of the new year - was dominated by exchanges on the NHS after a week of bad headlines for Accident and Emergency departments across the country. Increased demand resulted in several hospitals declaring "major incidents", and figures showed the A&E waiting time target had been missed for the last three months of 2014. Ed Miliband used all his questions to go on the attack, but David Cameron claimed the Labour leader had said he wanted to "weaponise" the NHS.

Hello and welcome to our live coverage of Prime Minister's Questions. David Cameron and Ed Miliband will go head-to-head in the House of Commons at noon.
