Has the witch-hunt over MPs' expenses gone too far? As they return to the Commons this week after their summer break, hundreds of MPs are due to receive letters from the auditor appointed to investigate expense claims over the past five years. They're being told to hand back money or face the consequences. Many are angry because they followed the rules, their claims were approved and now they're being told to repay because some of those claims are now seen as unjustified. Is this unfair? Or are our MPs out-of-touch with public opinion? Graham Stewart takes your calls, texts and emails.
