The current Alternative Vote referendum in the UK is besides the point. Whatever the outcome, the British “First Past The Post” system is fatally flawed. It may produce (usually) single-party government, but this is profoundly undemocratic, since a party obtaining only – as in 2005 – 36% of the national vote can form a government on its own. This is CONVENIENT (especially for the winning party) but UNFAIR.
Of course, in the current debate (such as it is) this point is completely overlooked, since it suits the large parties.
