The LibDems must be really thanking Paddy Ashdown for needlessly revealing that Charles Kennedy refused to shake Ming Campbell's hand after his speech on Tuesday. At a stroke, Ashdown demonstrated to us all that the wounds from Kennedy's overthrow are well and truly gaping open. I suppose Kennedy thought that if he shook Ming's right hand, his left might be used to stab him in the back again. Actually, what the refusal did was to display a petulance entirely lacking in his speech. If he truly does still harbour hopes of a leadership comeback he would do well to dispose of such things.
