The next contestant

Rona Ambrose takes another turn on the ever-popular Con game show, "Wheel of Specious Excuses":

Liberal Senator Grant Mitchell asked Ambrose for any studies to support the government’s contention that (the One-Tonne Challenge and Energuide) programs weren’t working...

Ambrose denied that any overall assessment of the climate programs had been done.

“There’s never been a comprehensive audit or review done of the climate-change programs across government, ever.”

Mitchell asked how, if there had been no review, the government could know the programs were ineffective.

Ambrose then said an assessment had in fact been done, “We did a comprehensive review, by PCO (Privy Council Office) of all these programs.”

The meeting ended amid jeers before the apparent contradiction could be resolved.

While the show may have some dark comedic value, that's wearing thin after repeated viewings. Which means that we can only hope that the routine gets put out of its misery before too long.
