From the Crikey grapevine, the latest tips and rumours …

Abbott stakes his claim. Stop us if you have heard this one before, but former prime minister Tony Abbott is no longer sniping, he's started all-out war with his successor Malcolm Turnbull, using his speech to the Institute of Public Affairs last night to launch "a plan to win the next election" on the homepage of his website. Of course he doesn't say "my plan", but he lets us fill in the gaps. The big headline is "let's make Australia work again," which shows just how much he loves one Donald Trump. His six points include things he can't do without a referendum, like "reform the senate" and others that aren't even policies like "celebrate Australia -- don't run it down". The further you read, the more it sounds like a down-ticket candidate for One Nation soon to be dumped for a scandal.
