Interesting ............... pure partisan horse droppings but interesting.

The reality is somewhat different.  Google Robert Coates, a former Conservative MND who resigned in 1985 over the mere appearance of impropriety.

Or how about Maxime Bernier? As a Minister under Harper he failed to properly protect sensitive govt papers in his possession.  He then promptly resigned as Minister of Foreign Affairs.

Sure you still want to go with your "denied until they were blue in the face." claim?

After all it appears you're struggling to respond to Joe Dick's invitation to back up your claim with fact.
