In Denmark, the left bloc won the 2022 election despite winning fewer votes than the right bloc, even though Denmark has a proportional system. The Danish system, like many in Europe, is a two-tier or proportional system. The researchers looked at different electoral systems around the world, both first-past-the-post like the UK, and proportional systems like much of the rest of Europe. In the UK, which has a first-past-the-post system, proportionality is the component which gets sacrificed. In 2024, Reform UK won 14.3% of the vote but won just five of 650 seats, while Labour won 411 seats on 33.7% of the vote.
