The government structure seems to be setup in such a way that any meaningful change is rejected.
Now the same crowd is turning their attention to the ECHR. It won't help.
I think it is a combination of many things. To make meaningful change each one of these entities (quangos) will have to be examined, reformed or reviewed.
I am not sure it is even possible for that to happen without a collapse and/or crisis at this point.
I listened to a podcast with Dominic Cummings last night and he is of the opinion that the UK government is extremely weak at the moment and if there was another black swan event that they would crumble. I don't know if that is true, but it seems plausible.
