As I mentioned before, we will probably end up with another hung parliament with nothing achieved.It's one of those things we probably need proportional representation...so the right and left have a voice at all times in the political process.
However neither side has any interest in not being able to absolutely impose their will while in power.
It would have stopped Boris having an unassailable majority...and it also would probably stop a Starmer majority as well.
But neither side wants to deal with the other absolute power and division between sides is easier to manage.
The PR system would give a more balanced representation of the Electorate and I suppose with the current system nothing much is achieved anyway.
