The 2010 election may have produced a very rare outcome where neither Labour or Tory for once gained overall control of the House of Commons. But the chart here shows just how similar the vote split was to the elections of 2001 and 2005.
Once again, the non-voter block (nearly 16 million) was by far larger than the largest party’s share (Tory, 10.7 million) and, as the following table shows, the vote share of Tory and Labour combined was pretty much as normal: just over two-fifths of the electorate.
Look at the very similar data for ‘Tory’ and ‘Other’ in the first three columns. There are only fractional differences between them. Then look at the all-important fourth and fifth columns which tell us about the split of the number of seats in parliament. Through the distorting machinations of our electoral system, the Tories ended up with over three times the number of seats. And Labour, who polled 1.75 million less votes than Others got just under three times the number of seats.
This underlines very well the message of the last four elections. Under our archaic first-past-the-post electoral system, power in parliament is proportional to the way it allocates seats, not to the voting intentions of the people.
