Every time you think 2GB broadcaster Alan Jones has gone as low as he can go, he sets a new benchmark ever deeper in his now obviously bottomless barrel.

Not enough that he has already talked of putting the Prime Minister “into a chaff bag and hoisting her into the Tasman Sea,” or that he has said that the country needs to “bring back the guillotine,” to deal with her, and that across the country “women are wrecking the joint". Now, before an audience of Sydney University Young Liberals last weekend at the Watermark Restaurant at Balmoral he has referred to the grieving PM's late father, John Gillard – a man who was obviously very close to, and extremely proud, of his daughter – and said that he, “died a few weeks ago of shame".

The unspeakably vicious nastiness of it, the sheer bully-boy misogyny of saying such a thing, simply takes the breath away, even for those of us who spent fair chunks of time around the unvarnished Jones.

Equally staggering is the reaction to his remarks: laughter amidst the gasps. But where was the person who did what needed to be done, which was to stand up and walk out, loudly protesting that by speaking in this manner Jones not only disgraced himself, but also the once proudly courteous party of Sir Robert Menzies? Where was the Sydney University Young Liberals President, Alex Dore, who had invited Jones to the function, publicly dissociating his club from those vicious words?
