Have MPs learnt their lesson on expenses? Graham Stewart continues his look back at the big phone-in topics of 2009. Whether it was claims for duck ponds or flipping of homes, the scandal surrounding our elected members' expenses posed one of the biggest threats to democracy in more than a century - and it was the issue you called us about more than any other this year.

Graham Stewart takes your calls, texts and emails.
