Labour Party leader Phil Goff is expected to stand down as leader of the party when Labour's caucus meets in Wellington on Tuesday.
Goff said yesterday he took responsibility for Labour's 27% share of the vote in Saturday's election.
Radio New Zealand polical editor Brent Edwards said this morning that, of the two front-runners for the job, he understood David Parker had the edge over David Cunliffe.
Many Labour MPs are apparently "furious at what they see as Mr Cunliffe's lack of support for Mr Goff" over the last year.
Who do you think should be the next Labour Party leader?
Should Phil Goff stay on as party leader?
Is it between David Cunliffe and David Parker?
Who else could be in-line for the job - Shane Jones, Grant Robertson, Andrew Little, Maryan Street, David Shearer?
