I want the government to change the system at all general elections from now on.

I think:
1.) There should be compulsory voting.
2.) A candidate must get at least 50% of vote share to win their seat. If a candidate gets fewer than 50% of the vote share, I think there should be revote between the top two candidates.
3.) "None of the above" should be added to ballots papers and if more than 25% of people in a constituency choice this option, new candidates must be chosen for that area.
