after an election), if 50percent + 1 of the caucus vote "non confidence" in the leader at any time, an ensuing leadership race will be decided by the 40/40/20 formula (members, caucus, affiliates)? Indeed that is my understanding Lanth. I believe the following is the rule (also known as the 40/40/20 rule) which applies no matter how it is triggered (40% or 50% caucus threshold). Rule 297A d) The election of the Leader of the Parliamentary Labour Party shall be determined by the votes cast in an electoral college composed of the following: i. Parliamentary Labour Caucus (40% of the total vote) ii. Party members (40% of the total vote) iii. Affiliate Party members (20% of the total vote). Voting will be preferential and concurrent in all cases. OK, so if a leader gives an interview to Ian Wishart 3 months before the election and says "White Power! Nuke the Darkies!", can the caucus choose an interim replacement, or do they always have to trigger a party-wide contest? Is there a "Mike Moore 1990? scenario, in which Labour MPs say "We've picked a new caucus leader, just before the election to try and save our skins", and it would then have to wait to be confirmed after the election? I'm sure it's in the fine print somewhere ... leaders can die in office, after all. I'm just wondering about the logistics of it. In Robertson's electorate Labour rank THIRD in the party vote -- oh dear!! Robertson may be "liked"
