None, as it transpired. The world's most anti-climactic interview crawled through its 20 excruciating minutes, each seemingly longer than the last, towards its inevitably dull conclusion. Bronwyn Bishop makes her lacklustre debut on Sky News. "I'm still very involved with things like the Sydney International Piano Competition, which is about to start on the 6th of July," she gaily revealed at one point. "Thirty-two of the world's best pianists coming to Australia." Speers, a double Walkley Award winning interviewer, desperately tried to track back towards a topic vaguely resembling federal politics. But on any subject which might have interested the commentariat, Ms Bishop fell somewhere between slyly blunt and devastatingly silent. On that fateful helicopter flight to a Liberal Party fundraiser, the one that ended up costing her career?

"It was just that we had to get there, the time constraints were there," Ms Bishop explained. "But as I said, it was a pretty dumb thing to do." David Speers tries without luck to energise Bronwyn Bishop. On whether she had spoken recently with Tony Abbott, the man who once described himself as the political love child of Ms Bishop and John Howard? "Not other than to say g'day." On her cryptic valedictory speech, in which she had promised there was "much more than meets the eye" to her resignation as Speaker and the collapse of her friendship with the former PM?

"It's still not for now. We've got an election that's raging, we've got so many more issues that are important to discuss. It's not all about me." On the simple matter of whom she voted for in the September leadership ballot? "Well the world seems to have made up its mind about who I voted for so why don't we just move on." To be fair to Ms Bishop, it wasn't all evasion and deflection. There were, as Celine Dion might say, moments of gold and flashes of light. She confirmed that Mr Abbott had asked her to resign, after much deliberation, following the Choppergate scandal - and that she had only decided to resign once he had asked.
