Kevin Rudd delivered a good spray on what Commissioner Cole can and cannot do on Lateline last night – but he didn’t get onto one very interesting topic. Why didn’t the Deputy PM get questioned about farmer’s friend Bill Heffernan yesterday?

Heffernan isn’t backwards in coming forwards. He takes a close interest in wheat. What did he have to say to Mark Vaile and his staff – or Vaile’s predecessors? Or the National’s deputy leader and former agriculture minister, Warren Truss?
