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
