In the house today

Helen Clark & John Key, back from parliamentary recess, appeared to subtly changed their styles. 

Helen Clark was a touch more conciliatory & actually addressed the questions rather than attacking John Key with condescending rubbish. 

John Key, on the other hand, adopted a more aggressive posture with a showmanship delivery. 

It was an improvement for both politicians.  I suspect Helen has been told to dial back her arrogance in Question Time, but she's going to find that hard with Key going on the attack.
