Well, not the best one, but here. The biggest issue is that Scotland and Wales are overrepresented in Parliament. Both also tend to heavily vote Labor.
Here’s a link that is a bit more explanatory. Scotland, Wales and Northern Ireland have guaranteed minimums for representation in Parliament. They are now overrepresented.
As for England, the rule is that, while equal-sized constituencies are best, “Parliament, however, determined that the ‘organic’ requirement to represent communities should take primacy over the mathematical requirement of equal constituency population. They removed the 25 percent deviation rule and replaced it with a rule that constituencies should ‘be as near the electoral quota as is practicable.’”, but representation of a particular community (town, county, etc.) trumps equal representation of voters.
Not only, as others have pointed out, do few Americans care about British elections, but I have the impression that few Brits care about them either. I was working in the UK earlier this year during the election, and I was astonished at how little attention they seemed to get. Nobody was talking about what was going on, the media seemed indifferent. The biggest news around election day was the 60th anniversary of the end of the war. Coming from having witnessed the US election the previous year, where everyone and his mother had an opinion and wanted to express it, the difference was shocking. And they call Americans sheep!
That cite and site are out of date. Scottish representation has recently been reduced from some 72 to some 59 seats- this was the main imbalance.
The major problem now is that the Tories have too many wasted voters in England- rural constituencies with high majorities and that there are fewer marginals. In fact the Tory vote in England was higher than the Labour vote in 2005 but Labour still gained more seats because of its better distribution of voters.
Not the bloke who used to be on Sport on Two (dada-da dada-da dada-da dada-da da, DA DA, dada-da etc), then did TV after Icke was beamed up, then went off to do an Alastair Campbell for the FA?
Is the comparative populations of constituencies still a problem? On reading my (outdated) cite from my last post, it seems that the UK puts a great deal less emphasis on equality of population in voting districts than the US does.
