According to the information booklet from The Electoral Commission, and the way I read it at least, there's a possibility that even if the referendum on the alternative vote goes the way of the yes vote, there's still a chance that it might not be implemented.
To quote from the information booklet:
"The 'alternative vote' system will be used after a review of boundaries of the area that each MP represents (known as their constituency) is completed. This is due to happen between 2011 and 2013. The review will happen regardless of the outcome of this referendum.
At the end of the review, the UK Parliament will vote on implementing the new boundaries. If the new boundaries are implemented, the 'alternative vote' system will be used for all future elections to the House of Commons."
Is it just me being cynical/paranoid, or could this also read "If the new boundaries are not implemented, the 'alternative vote' system will not be used for elections to the House of Commons"?
Time to visit www.aboutmyvote.co.uk to try and find some contact details for clarification on this point.
