With news that Labour's four bent lords are not to face criminal prosecution for corruption, and that the Home Secretary will not face a standards investigation for snaffling dodgy expenses, it may appear that there's plenty of ammunition there for David Cameron to fire at Labour. But will he?
Peter Oborne believes that the political class have more in common with eachother than they have with us, the voters. If he is right, then Cameron will be disinclined to make political capital out of Labour's sleaze. MPs as a body may also be of the view that public intrusion into their misbehaviour has gone too far, that it's time to close ranks, and that refusing to take action against bent MPs uncovered by the media or bloggers is the best way to stop all the probing.
If there's a scintilla of truth in the above, it will do MPs and their dying parties no favours. The public have never been so far removed from the world of the political class, have never been more cynical about politicians and their dags, and have never been more disillusioned about standards of probity in Parliament.
I sincerely hope Cameron will declare his stand against sleaze, and excoriate Labour and any members of his own party found to be corrupt. But I won't hold my breath.
