There is very little that I agree with Jeremy Corbyn on. All those years ago his capture of the heart of Labour was the principle reason I left the party.
So what I say now should in no way be construed as support for him or his ideology.
Mr Corbyn has a following. It is a following that I find a little strange but it is also one that is principled and not insignificant in size. On that basis only it is good to see him launching his new political party, whatever it is called and despite all of the internecine battles.
There is every chance that in the wider population at least 10% of voters will cast their ballot for Mr Corbyn's platform, and it's absolutely certain that at the next election they will not get the number of parliamentary seats commensurate with that level of support.
Our First Past the Post system of elections is inequitible beyond belief.
It was a system that was set up to provide constituency level representation in a two party system, whether those two parties were Whigs and Tories, Tories and Liberals or Tories and Labour.
But we no longer live in a two party world.
By any measure, and not factoring in parties calling for national independence, we now have at least a six party system: Labour, Conservatives, Liberal Democrat, Green, Reform UK and Mr Corbyn's vehicle.
Our parliament is now elected using a system where just over 30% of the popular vote (and much less of the overall electorate) can deliver a landslide. It did for Labour in 2024 and will, potentially, do so for Reform UK in 2029 on an even smaller share.
Not only is that not fair, it is the path to unrest. If our political system is based on the consent of the defeated it cannot be defensible that the defeated equate to three quarters of the population.
The answer is a parliamentary system that is fairer in distributing seats based upon vote share. The answer must be one of proportional representation.
If Mr Corbyn's party earns 10% of the popular vote it is not unreasonable for him or his voters to expect comparable representation in our legislature.
If this Labour government wants to deliver one lasting constitutional innovation then at its conference next week it should announce a move to PR. They could proudly be the last government to be elected on a 30% vote share, and would undoubtedly continue to be a major force under any new model of representation.
