If you mean they've gone way beyond Major in terms of pursuing awful policies; I'd agree.
however, if you mean in terms of personal; corruption, that simply isn't true.
There were 23 resignations/sacking forced by scandal in the major era.
There have been NOWHERE NEAR as many with this lot.
In fact, all I can recall - off the cuff - are;
1. Ron Davies; an affair simply too bizarre to judge, IMO.
2.Mandelson; guilty of a relatively minor offence first time, and probably NOT guilty of what he was accused of, second time round (a report exonerated him); in fact, his true crime was to be so loathed by all his HoC collagues (bar one) that no-one chimed up to support him.
3. Bev Hughes - lied to the house, has to go, but hardly Hamiltonesque sleaze.
4. Blunkett-guilty as charged, but again, only due to the code of conduct introduced by new labour, in response to the scandals of the Major years.
In fact, more ministers (including PPS's) resigned over Iraq; 11 in all, if we count Short's monumentally-botched one.
Don't get me wrong; i loathe Blair & Co. It's a tragedy no-one's nailed their lies over Iraq.
But you do yourself a disservice with wild, haymaker accusations like these.
it damages your case, which is a shame.
