Unfortunately I still don't think proportional works with electing an MP for a constituency. I would change the commons elections to transferable vote system, which would allow more people to vote for their first choice and reform house of lords so that it is elected proportionally
Depends on the version of PR, and how "pure" the PR bit is.
Personally, I think I'm in favour of an adaptation of the Kiwi system.
If I've got this right:
You have
X seats for a
region, of which half are constituency MPs that are elected with FPtP as per normal. The other half are then filled up from the best performing losers in such a way that total
X is fully proportional (andnot just flown in by the party's preference).
A party only gets into the PR portion if they ran candidates in every consituency within the region (so SNP do for Scotland, PC do for Wales, Count Binface doesn't for wherever he stands).
Sensible to add transferable vote in there as well, which would boost the representational value of the PR portion.
To take a fictional region in England, and let's call it... Central.
Central has 60 seats in Westminster, split into 30 constituencies.
Those constituencies get their seats filled by FPTP, winner takes all.
Which may end up as Con 3, Lab 24, Lib 3, Reform 0, Green 0
But with a vote split of Con 23.3%, Lab 44.7%, Lib 9.2%, Reform 11.8%, Green 5.8%, Other 5.2% (this "Other" really doesn't help the maths)
The losing candidates for each party in Central, are arranged in order of vote share locally
The 12 best performing, losing Conservatives candidates, get a PR seat for 25.0% regional representation
The 4 best performing, losing Labour candidates, get a PR seat for 46.7% regional representation
The 3 best performing, losing Lib Dem candidates, get a PR seat for 10.0% regional representation
The 7 best performing, losing Reform candidates, get a PR seat for 11.7% regional representation
The 4 best performing, losing Green candidates, get a PR seat for 6.7% regional representation
Each constituency gets the most popular local MP
Each
region get represented proportionately, with the MP based on the vote share of each candidate.
Personally, of courses, I'm in favour of devolved power (about the same as Scotland's) to the 9 English regions anyway (and bringing Wales and NI up to the same power-level), with elections as above, and then PR representation from each regional parliament to Westminster for national issues. But that's me.
