Bill always had delusions of granduer.
Leading the unions, slush funds, private jets, access to "mummy" at Yarralumla for high tea, thought he was moving into the Lodge, etc etc.
London to a brick he hasn't given up on his delusions and would leap at the opportunity to be ALP leader again.
Due to rule changes it won't happen unless our Handsome Boy either quits (won't happen) or ALP lose the next election.
