Important context since this is about the UK: we don't have a representation seat distribution like that, we have first past the post. In the last election (2019) these are the results for each party with at least 10 MPs:
- Conservative Party, 43.6% of votes, 56.2% of seats (outright majority).
- Labour Party, 32.1% of votes, 31.1% of seats.
- Scottish National Party, 3.9% of votes, 7.4% of seats. The SNP only campaign in Scotland and win most seats there, which makes them extremely over-represented by FPTP.
- Liberal Democrats, 11.6% of votes, 1.7% of seats.
