To the list of credibility-deficient statements like "the cheque is in the mail" and "your table will be ready in a few minutes" you can now add "Murray McCully is not a micro-manager".
In the Foreign Minister's absence - McCully was heading for China yesterday - another minister, Chris Finlayson, drew the short straw in having to answer questions in Parliament on McCully's behalf as the Opposition continued to press its attack over the botched restructuring of the Ministry of Foreign Affairs and Trade.
Finlayson had been making a reasonable fist of deflecting that attack until he suddenly made his hard-to-swallow statement about McCully's management style.
McCully has been the power behind more thrones than Robespierre and Rasputin combined. The picture painted of McCully as some political innocent oblivious to the goings-on in his ministry had the Opposition benches in stitches of genuine laughter.
Finlayson only raised the mirth quotient when he added: "His name is McCully. Not Stalin or Helen Clark."
