Party Efficiency
Reform were the most efficient party. They won 8 seats, and in the wards they did not win they were mostly 3rd or 4th. Their vote was concentrated exactly where it needed to be.
The Lib Dems were almost as efficient. They won 3 seats, had no second places, and only one third place, in Portswood. Everywhere else they were 4th, 5th or 6th. That is classic Lib Dem targeting: don’t waste votes everywhere, win where you’re organised.
The Greens also targeted well. They won 4 seats and had one second place, in Swaythling. Everywhere else they were mostly 3rd or 4th. Their vote was less efficient than Reform’s or the Lib Dems’, but still converted well.
Labour were spread all over the city: 2 wins, 8 runner-up spots, 5 thirds, one 4th in Swaythling and one 5th in Bassett. That is the profile of a party with residual support almost everywhere but not enough concentrated strength to win many places.
The Conservatives had the worst conversion. They won no seats from 10,013 votes and 16.7% of the citywide vote, while the Lib Dems won 3 seats on 8,447 votes and 14.1%. The Tories had 7 runner-up spots, so they were often competitive, but not quite in the right places. That is a targeting failure as much as a vote-share failure.
Finally
Had the vote splits hurt either bloc, actually no, if you added up Labour, Lib Dem and Greens on one side and Reform, Conservatives on the other side, nothing would change, The Right Bloc would have 8 seats (all the ones Reform took) and the Left Bloc 9 (all the ones Lib Dems, Green and Labour held).
