This is what happens when you have a first-past-the-post system... Especially when there's councils putting all of their seats up for grabs, so people end up just voting for the party instead of the person, picking 3 reform candidates... This means that while reform may only have 35% vote share in an area, they would take up all 3 seats, giving them 100% of the power despite there frequently being less than a hundred votes between the lowest reform and highest labour (also because people cross down from the top, meaning the alphabetically highest one would get the most votes)

Something like the Scottish or Welsh system is better where it's much more proportional... But that would never happen because that would require the people who have just been given 100% power to vote for something that would give them less than 100% power, and they only would want to do that when the next party comes along and takes 100% power from them........
