The resignation speech of the Conservative Treasurer Cruddas uses a technique fashionable among the PR and customer care community
He apologises for an "impression of impropriety".
It is the same formula used by those who write and say "We are sorry that you found our service less than satisfactory"
In both cases it restates the specifics of a charge into an abstraction (e.g. "late train" becomes "service below the standard you had expected" just as "selling access to the Prime Minister" becomes "an impropriety" AND it seems to apologise, because it uses some of the diction of apology, but is in fact expressing regret for the complainant's state of mind.
It distracts you from the crime and from the culprit. The expression of concern for the complainant -- I am sorry that you found our service to be below standard -- is just a mild form of locking up dissenters in the asylum: you disagree with us, therefore you are wrong / mad.
It is a further dishonesty.
Francis Maude's suggestion on Sunday -- some or other radio programme -- that Cruddas resigned because he had boasted and said things were not true is a further dishonesty. He resigned because he was recorded being perfectly honest, though we might well consider his proposal, that about which he spoke with candour, to be dishonest.
