Constituencies, First-Past-the-Post and Minority Rule

The other day, I re watched CGP Grey’s excellent videos about the Electoral College. In one video, Grey shows how it is possible to become President with only about 23% of the popular vote. The UK’s constituency-based system shares some key features with the Electoral College, so I wondered whether a similar feat might be possible here. A quick search for data and a few lines of code later, I had my answer.
