I saw a post in regards to the proportional voting and how it would have turned out (I think it was from AJE)
Under proportional representation,
"Reform UK would have won 14 percent of seats in the House of Commons getting 14 percent of votes, a significant number – 91.
If the PR system were in place, the Conservatives would have won 156 seats, and the Labour Party would have won 221 seats (crucially, not an outright majority).
The Greens would have won 45 or 46 seats; the Liberal Democrats, 78 seats; Plaid Cymru, six or seven seats; and the SNP 13 seats.
