Yesterday's question time in Parliament witnessed one of the severest grillings that John Key has faced from Opposition parties in his near five years as Prime Minister.
Not that you would have picked it from Key's seemingly relaxed demeanour while being peppered with questions about his office's role in the David Henry inquiry into the leaking of the report by Cabinet secretary Rebecca Kitteridge on the workings of the Government Communications Security Bureau.
Key was cucumber cool - just as he would have been back in the days when he was operating in the nerve-frazzling. high-pressure world of currency trading.
But behind the placid facade there were plenty of clues that he well understood the pickle he faced if he failed to reconcile emails which Opposition parties claim show Key's office was donkey-deep in efforts to seek the phone and other records of Andrea Vance, the journalist who was leaked the Kitteridge report.
Key's usual flow of wisecracks and putdowns during question-time had suddenly dried up. That was replaced by Key the Helpful as he explained why emails from his chief of staff, Wayne Eagleson, should not be interpreted as instructing the Parliamentary Service to submit Vance's phone records to the inquiry.
