I see what you did there.
He can't be removed if he's sitting in the HoL, can he?
And, even now, are you suggesting that we can get rid of him, but only if we unseat the prime minister first?? And only then if his successor's whim is to kick him out of his job? Since he is calling all the shots right now, that's some control you think we have!
Parallels are perfectly reasonable since the usual dig at the EU - a dig that was crafted by the man in question - is that it is "full of unelected bureaucrats" that have undue influence on our lives.
EU Commissioners are nominated by democratically elected representatives of member states. This is a civil service role in a similar manner to that under which Cummings currently operates yet you seem to think is fine. The only difference is that EU scrutiny is much more arduous than Boris putting his minder into the top job because they first have to be scrutinised by democratically elected members of the European parliament before they take a vote on their suitability. We vote in the European parliament.
So, when you look at the facts and the detail, there is indeed a difference. I doubt very much that a megalomaniac like Dominic Cummings would pass such scrutiny, do you?
The EU is more democratic that the UK - fact.
