David Shearer has strenuously denied there are moves afoot within his own caucus to have him dumped as Labour's leader - and senior colleagues are backing him up.
Parliament was abuzz last might with rumours that some MPs have drafted a letter of no-confidence in Mr Shearer.
Labour MPs contacted by the Herald dismissed the talk - one as "horse***t'' and another as "bull***t''.
But it is also evident that Mr Shearer is not on safe ground.
Some MPs conceded that there is anger in the party organisation particularly in the way he ditched the proposal for "women-only'' selections which was to have been debated at the November conference.
