Politics Weekly podcast: MPs' expenses, AV and smoking

This week we hear the final verdict from Sir Thomas Legg on the MPs' expenses scandal . Journalists may be tired of the story, but Catherine Bennett thinks the public has an insatiable appetite for it. This week Gordon Brown finally asked parliament for a referendum on electoral form . So what does our panel think of the proposed Alternative Vote system? Nick Cohen thinks it's just a ploy to woo the Lib Dems and that it's a potty idea and Michael White , who sat in on prime minister's questions this week , tells us that it's business and that maybe we are heading for a hung parliament. Finally we discuss the government's proposals this week to crank up their campaign against smoking . Cohen is incensed, calling it Fabian control gone mad. Tom Happold however, thinks it makes sense for Labour as it is their people who are dying.
