Why Prescott should go:
He brought his office into disrepute (made it a laughing-stock);
He has flouted duty of care towards a subordinate - if he were in uniform he would be court-martialled;
His actions are in flagrant disregard of equal opportunities training;
He has indulged his affair using government resources;
He cannot be trusted or viewed with any credibility at all.
Were you saying this about John Major in his Edwina Curry phase? All of the above accusations could be laid at his feet, or is your real problem the fact that labour are in power?
Just to turn your argument back on itself
Why Maggie should go:
Presiding over a shambolic government;
Lying over The Falklands (I can revisit that argument if required);
Making a catastrophic misjudgement in following Ray-Gun’s lunacy;
She ignores the sacrifices of the Armed Forces by refusing to visit the wounded and bereaved unless it's a good photo opportunity
The public simply do not trust her
My point being that if you use any convenient stick to beat a political opponent you either apply the same moral standards to all or you end up looking like a hypocrite, that's not much of a problem if you're a private individual, as we all are to some extent, but if a so called 'news' organisation sets itself up as the moral guardian of the country and (unelected) opposition as the likes of the Daily Mail do, perhaps we should expect honest straightforward reporting rather than agenda setting?
And prehaps the journos that work for such papers should be expected to live by those standards they would impose on everyone else - Did Piers Morgan resign on a matter of honour after presiding over the Iraqi ‘torture’ fiasco? Did Boris Johnson resign over his serial affairs when running the Spectator?
