If the Labour party stands for anything it should stand for these things.
So when Jack Straw and others in the Labour party say PR doesn't deliver, frankly they are talking rubbish.
When Labour reneged on their manifesto commitments to have a referendum on PR, they failed the British people.
Despite 60% of voters consistently voting for left of centre, redistributing and tax increasing parties, this system has instead given us regressive tax cutting Tory governments most of the time. Never has there been 50% support for regressive tax cuts despite the best efforts of the right wing press to persuade us.
Yet still Labour members close their eyes to reform in favour of their tribal instincts.
Cameron masks his cynical and partizan policies as if improving democracy. £50k limits on trade union donations to destroy Labour funding while foreign billionaires secretly fund the Tories. Reducing the number of MPs to 500 (to maximise the effect of the Tory rural vote) despite the UK already having the lowest number of elected officials per head in Europe. These policies are clearly designed to increase Tory MPs not democracy.
Unless we change the electoral system now from a position of strength we might once again face decades of regressive government and it will be the British people who will pay the price for our cowardice.
Left of centre policies will definitely benefit under PR (the evidence for this is clear worldwide) and the largest left of centre party, us, should benefit as well. What are we scared of?
Finally to those who think a hung parliament will bring PR. Replacing Labour MPs with Tory MPs who are universally hostile to PR will take us further away from PR not closer. Only persuading a majority of MPs of a Labour government will bring PR (just like it did in New Zealand - and Labour there have increased their vote with each of their 3 victories, unlike us who have lost nearly 5 million votes). The best thing Lib Dem members could do to bring PR is a mass defection to Labour and voting for a PR friendly Labour leader in our leadership election. Think about it.
