"Gordon Brown is to introduce a law to guarantee that a re-elected Labour government would hold a referendum within two years on abolishing Britain's first-past-the-post system for elections to the Westminster parliament.
Electoral reformers hailed the move to abolish the winner takes all system which gave Labour 55% of the seats in the House of Commons in 2005 on an overall share of just 35.3% of the vote.
Ministers are to introduce paving legislation within months to ensure a referendum by October 2011 on replacing the first-past-the-post system with the Alternative Vote (AV) system.
Under the current system voters place an X against the name of just one candidate; the winner is the candidate with the most votes. Critics say the votes for other candidates count for nothing."
