Well, civil servants aren’t elected. Which is a good thing. You can’t elect everyone.
I think Cummings is on the right lines here but as I said earlier he needs to calm down a bit
The first flush of success will soon fade and it will inevitably be watered down so nothing much will change or happen to upset the civil service bubble.
The civil service doesn’t “block” the government. What a ridiculous idea.
However, if much needed reforms are handled badly you might expect a less than cooperative response.
