One of the most enjoyable games in Canberra currently is trying to work out who was behind, and who benefits from (two separate questions) the leaks that regularly drip from this shambles of a government. Yesterday someone decided to ruin Julie Bishop's carefully prepared "innovationXchange project" announcement, for which she'd co-written an op-ed for The Australian, by telling Tony Abbott's close friend Greg "George W. Bush will be judged one of the great presidents" Sheridan that her foreign aid budget was going to be cut.
