The Voter Power Index is based on research by NEF (the New Economics Foundation)

If the UK had a proportional voting system:

  • We would no longer have safe seats
  • The power of votes would be much more equal
  • All areas of the UK would have equal power to decide the outcome of the election
  • Politicians would not be able to win an election by tailoring all their policies to a narrow section of the population
