MP's and their expenses

Let’s reward our MP’s.
Why pillory them for their peccadilloes when they have gone beyond the call of duty (as in the synonym for tax) in providing us with such enterprising entertainment?
Instead, let’s grant immunity from prosecution to those MP's who come up with the most imaginative justification for their fibs and foibles.
David Heathcoat-Amory, for example, the Minister with irresponsibility to procure manure, might have argued that he was about to table a ‘motion’ in the Commons. David Cameron could be commended for doing his part to keep in check the mass wisteria surrounding this whole tawdry issue – while keeping his gardener in even bigger cheques.
And for those who fail to amuse, make the punishment fit the crime. A good start would be to de-moat Douglas Hogg.
I put the motion to the house.
Before it flips altogether.
