The ALP has a new leader, Bill Shorten, who trailed in the member ballot but pretty much swept the caucus ballot. Shorten has form from the Gillard coup and the Rudd coup but obviously enjoys the confidence of his parliamentary colleagues. The new electoral process, a joint ballot of party members and MPs, worked well.
A small glitch is that Shorten is married to the daughter of the governor-general who offered to resign to avoid any appearance of bias. The PM issued a statement saying that he has rejected the resignation, although that may be news to Elizabeth II.
It looks like the ALP will probably extend its democratisation experiment to internal primaries and the election of state Labor leaders.
