Thanks to Hopi Sen for pointing out that David Cameron is himself a housing benefit scrounger.
David Cameron believes that housing claims of over £20,000 a year are unfair. He has a point. I can think of one benefits scrounger who has repeatedly claimed more than this, despite having a perfectly adequate home in London.
David Cameron Second Home Expenses: 2003-04: £20,328, 2004-05: £20,902; 2005-06: £21,293.86; 2006-07: £20,563.
