Do I rate her highly? Or do I rate Grayling and Shapps so lowly that they're heading for the Mariana Trench?
Grayling's decision to cancel the electrification of Bristol and Oxford's railways cost far more than it saved, once Hitachi had been bunged a considerable sum for fitting diesel engines to the electric trains. Bristol remains swamped by polluting diesel trains.
Shapps went out of his way to piss off railway staff, just for the sake of doing so. He spent months refusing to let the operators negotiate with their staff who were several years into a pay freeze during a period of high inflation. Then claimed that it was nothing to do with him (liar - the words "Secretary of State" are littered through the National Rail Contracts, the Managing Directors can't fart without written permission in triplicate from Whitehall). His bloody-mindedness caused a great deal of economic damage, and resulted in a higher pay deal and less opportunity for restructuring than if the government had got on and made an offer before inflation rocketed. He's the reason that Northern Rail and Avanti are in the state that they're in, if you don't employ enough staff to run your operation without recourse to overtime then you'd better keep them happy enough to want to come in on their days off.
In that context, even Howling Laud Hope would have been a breath of fresh air.
