A parliament that cannot initiate legislation and not even completely refuse legislation introduced to the session. Very weird.
In UK analogies it's more like the house of lords except it has less revision power on the legislation before it.
The fact is not everything was the EU's fault. There was a lot Westminster could have done to make things better. They choose not to and indeed actually gold plated many EU directives due to virtue signaling which made them much more difficult to follow.
The fact is politicians at all levels including EU take credit for things they didn't do and try to ignore the fallout from things they did.
All the while blaming the voters.
Mainly because changing public perception of policy choices takes time and effort and they have limited of both and tend to want to focus on things they actually care about.
