Immigration has been the key talking point in the Rochester campaign and the issue could rear its head during the leaders' exchanges. Labour has said, if elected next year, it will require new EU migrants to wait two years before they can claim certain benefits. Former prime minister Sir John Major has also been talking about the issue, urging the EU to strike a "pragmatic" deal to allow the UK to temporarily control levels of EU migration until the eurozone's economic prospects improve.

So, what can we expect today? Well, voters go to the polls for the Rochester and Strood by-election on Thursday so expect references to the impending poll to crop up at some point. The Conservatives are trying to prevent defector Mark Reckless from winning the seat for UKIP while Labour is hoping for a decent showing.

It is the first PMQs for a fortnight after the leaders had last week off for a short Commons recess. In that time, David Cameron has flown to Australia and back for a G20 summit while Ed Miliband has made a major speech setting out what he would do in Downing Street amid recent criticism of his leadership.

Hello and welcome to our live coverage of Prime Minister's Questions. David Cameron will face Ed Miliband as usual from midday, while backbenchers will also have the opportunity to question the prime minister.
