Key backer Mark Mitchell says he believes Mr Luxon - who has endured poor personal polling and a run of unfortunate gaffes - will survive that meeting and continue on. If a no-confidence vote succeeds, Mr Luxon will be replaced inside three months of the November 7 election. Adding intrigue to Wednesday's meeting, there is no obvious contender to replace Mr Luxon. Many argue National's popularity slide is down to Mr Luxon, who has shocking personal favourability ratings. Mr Luxon has failed to land either pledge, and has rubbed many the wrong way with a series of elitist or out-of-touch comments.
