Mr Miliband changes his line of attack, on to his proposed "mansion tax", askingwhy someone who has bought a £140m house should pay the same council tax as those with those on middle incomes.

In response, Mr Cameron says people in such a situation can get support from the government's hardship fund.

Mr Miliband refers to a High Court challenge to the housing benefit reforms from a rape victim who is arguing against cuts for those who have had their homes adapted to protect them from a violent ex-partner.

On housing benefit changes dubbed by critics as a "bedroom tax" - Mr Cameron says the reforms are a matter of "basic fairness".

Mr Cameron responds with a joke about his Labour counterpart's leadership credentials. Mr Miliband asks why the PM is so in favour of the "bedroom tax and so against the mansion tax".

Ed Miliband is now on his feet, to jeers from the Tory side. He responds by saying "let's see if they are still cheering on Friday" - a reference to the outcome of the Rochester by-election.

The first question comes from Labour's Graham Jones. He asks about the chance of further Tory defections to UKIP. In response, Mr Cameron points out his party is the only one offering a referendum on Europe.

David Cameron is on his feet. He begins by condemning the "senseless and appalling" attack on a synagogue in Jerusalem.

The BBC's Nick Robinson tells Daily Politics other parties would be "absolutely crucified" if they had made comments like Mr Reckless' on immigration, adding there is a tension between "authenticity and not appearing extreme".

On the Daily Politics, Andrew Neil is having a bit of fun with claims that George Osborne has a lock on his Treasury fridge to keep his milk safe. The Conservatives have denied the suggestion - made by Mr Osborne's Lib Dem Treasury deputy Danny Alexander.

It was the end of an era in the Scottish Parliament on Monday as Alex Salmond took part in his last First Minister's Questions. With new Scots First Minister Nicola Sturgeon taking the reins on Wednesday, it will be interesting to see whether SNP members use the occasion to welcome her and how David Cameron responds.

The Commons is beginning to fill up. Chief Whip Michael Gove and Commons leader William Hague are in their places as Cabinet Office minister Francis Maude answers questions about his department's responsibilities.

Labour's Emma Reynolds tells Daily Politics that Mr Reckless' comments were "very worrying", claiming that he came "perilously close" to advocating repatriation. And for the Conservatives, Treasury minister Andrew Leadsom says UKIP's approach is "incoherent" and the only way to reform immigration rules is by remaining within the EU.

Mark Reckless, UKIP's candidate in Rochester, has come under fire after appearing to suggest EU migrants living legally in the UK might only be able to stay for a "fixed period" in the event of the UK pulling out of the EU. UKIP's immigration spokesman Stephen Woolfe tells the BBC's Daily Politics that there was no question of anyone being deported. EU citizens with a legal right to be in the UK, he says, will be able to stay and would not have to apply for a work permit.

On a more light-hearted note, Home Secretary Theresa May is on Desert Island Discs - a rite of passage for politicians with leadership ambitions - this Sunday. And continuing the musical theme, former Hear'Say singer Myleene Klass has criticised Labour's mansion tax plans, prompting Ed Miliband to describe the idea as "Pure and Simple" - a reference to the party's number one hit.

The economy and the NHS are always popular topics for David Cameron and Ed Miliband to dwell on respectively. The prime minister has been warning about the state of the global economy this week and its implications for the UK's recovery while the "major incident" declared recently at Colchester Hospital has highlighted again the pressures on the health service this winter.
