The United Kingdom uses the first-past-the-post (FPP) voting system for its general elections, which ensures that, election after election, the Conservative party or Labour party leads the government, with the other in opposition. These parties would be the ones who would have the power to change the system but, because the system benefits them, they naturally choose to keep FPP. This creates a vicious cycle and means that, election after election, FPP becomes further and further entrenched. For those who support voting reform, what can they do?
They could vote for a party that supports a proportional representation (PR) voting system but, due to FPP’s winner-takes-all setup, their vote would likely go to waste. They could also wait for the next hung parliament, and hope that a smaller party has enough influence (and determination) to hold a referendum on a PR voting system, but this depends on the luck of hung parliaments, and on the negotiating decisions of existing parties. So what options are left? If there is majority support for replacing FPP with a PR voting system, is there a systematic approach that supporters of voting reform could follow to bring about this change?
