Once again we see a particularly British problem.
The conceit that a completely unqualified "trier" can walk into he top tier of a technical (whether financial, IT or manufacturing) enterprise, and then succeed through positivity, connections and force of will.
Here's Cameron who claimed he knew all about the business and could punt its services to government.
Now it's gone tit-s up he's all "I don't understand this tricky finance stuff, don't blame me".
I'll float a couple of similar cases - the first particularly close to my cold dark heart.
The Project manager who insists on rigid control, usually enforced through rationing information to the implementors.
When it all goes tits up it's "I'm not technical, it's up to you to spot and resolve those issues".
Or a recent one.
The Brexiteers, with "They need us more ...", "German car manufacturers" and "Think of the fishermen".
Now it's all going tit's up it's "Remoaner saboteurs", "Barnier!!!".
