Sadly, McGrath, I fear you are right again . .
Sequestration of his lovely mansion in Granchester would have been far more effective . .
However I can't say I feel there's much wrong with the sentence, after all Perverting TCoJ could include obtaining a false verdict in a murder trial . .
And I reckon a spell in the squalor enjoyed by "guests of her majesty" would be good for all our politicians, since they seem to think there's nothing amiss with our prisons . . except, as McG again points out, he's unlikely to be in one of those prisons . .
