30 January 2013 Last updated at 12:59 GMT

Labour MP Alex Cunningham has asked the prime minister if "traces of stalking horse have been found in the Conservative Party food chain".

Mr Cameron responded to Mr Cunningham's "ingenious pivot" by saying the Conservatives stood for people who work hard and get on, and he was pleased that "all of those behind me take that very seriously."
