My view is that people elected to Parliament ought to be of reasonable intelligence. OK, that fails right there. We often elect nincompoops who are not fit to run a whelk stall. 30p Lee springs to mind.
What they ought to be doing, as part of their job, is to bone up on any complex matter put before them. They ought not to act on mere ignorant prejudice. OK, that fails right there.
Thirdly, if they become a minister, they should listen carefully to the advice of the professionals put in place to advise them. Just as any competent senior manager does - except, I suppose, those with genuine professional knowledge of their field. Generalists need to know how little they know. And 99 times out of a hundred, a minister is a generalist. And that is being polite. When did we last have a medical practitioner as Secretary of State for Health or a teacher as Secretary of State for education?
This, in a way, is how it should be. The minister is there to represent us, not the profession. But they should be aware of their limitations. For example, I have read an awful lot of military history, but I should be very reluctant indeed to tell a general how to fight a battle. It would be both presumptuous and absurd.
They do not have to accept all the advice they are given; but they should consider the possibility that it is not some labyrinthine lefty plot to obstruct them. This is where the idiot Truss and her sidekick went wrong.
