I’m not sure about this, but it seems to me pretty likely that Abbott won’t be PM on July the first.
He’s already behind Shorten as preferred Prime Minister, and ICAC may show him, soon, to have been involved in funneling money into the slush-funds of his party for fifteen or sixteen years.
Many of his caucus think him mad. He will be made to resign on the grounds of an unspecified illness, and Hockey elected unanimously to succeed him. Hockey will sack Morrison, expel Sinodinos, and make Corman Treasurer.
