Preston Manning had an astringent warning for Canadian conservatives at the annual gathering sponsored by his eponymous think-tank.

“For conservatives, being right must mean more than just being right of centre. It must mean doing the right thing. There is no substitute for rock solid personal integrity,” he told the large “C” and small “c” faithful at the recent Manning Centre conference in Ottawa.

Though the words were delivered with Manning’s characteristic personal geniality and intellectual charity, their sting was palpable, particularly among those Conservative Party members still writhing after being flayed by National Post columnist Andrew Coyne. Coyne had carved the Conservative government’s political, policy and ethical failings with the surgical scrupulousness of an assembly line sadist handling the Friday night crowd at Mistress Cheri’s House of Pain and Shame.
