This latest site sets out how much each MP costs the taxpayer and how often MPs vote. They then calculate a “cost per vote” figure, by dividing the total costs per MP by the number of votes he or she has recorded. For those constituents interested, I am rated as 3rd cheapest at £633.07 per vote. The average cost is around twice that figure. The MP ranked 11th dearest or 639 in the cheapest rating weighs in at £6,223.29 per vote.
