Asked if this was likely to prove his only shot at the leadership, Mr Cunliffe said he had "a whole lot of summer barbecues and more than one or two cold beers ahead of me before I even approach that kind of question."
"I am pledging complete and total support to the new leader of the Labour Party. I have no leadership ambitions at this point."
Given past tilts at the Labour Party leadership (most notably Phil Goff's attempt to roll Helen Clark), the "whole lot of summer barbecues" comment is probably not going to give David Shearer too much comfort as he settles into the role of Leader of the Opposition.
Nor will Shearer likely be reassured by Cunliffe's statement that the latter is "right behind" the new leader. If David Shearer has read Julius Caesar, he'll be well aware of the need to beware the Ides of March!
