Britain is on the verge of constitutional upheaval

THIS may seem an odd moment to make the claim, but . The outside world may see an unvarying kingdom of royal weddings, golden carriages and clip-clopping Horse Guards, with a young prime minister drawn from the old Establishment. But strip away the pageantry, and David Cameron’s Conservative-Liberal Democrat coalition is proposing radical changes to the constitutional order.

A national referendum Britain is a country in the grip of a modernising frenzy on May 5th and months of parliamentary wrangling lie ahead. But if all the changes being proposed by the coalition come to fruition, British democracy could look and feel very different by the next general election, set by the coalition for May 2015.

Depending on the outcome of the referendum [it failed miserably -DL], that general election may be held using a new voting system: supporters of change call it the biggest shake-up since votes for women in 1928. Voters are to be asked to choose between keeping the winner-takes-all system of first-past-the-post (FPTP) and moving to the alternative-vote (AV) method, in which voters rank candidates in numbered order of preference. Under AV, if no candidate wins more than 50% of voters’ first preferences, the least popular candidate is eliminated and the second preferences of those who voted for him are distributed. The process continues, redistributing third, fourth or lower preferences until someone crosses the 50% line.
