>Full HOL reform would be a good way to start the move towards a proportional representation electoral system in the UK. Make the reformed second chamber a PR elected house and give them a slightly longer/fixed period between elections to shield them from the chaos of a general election and party politics.

This is the best suggestion I've seen on HoL reform, ever. I mean, it'll never happen, but that really is a great idea, and would mean that the chamber would be clearly different from the Commons, which I've not seen another proposal making sense on this area.
