The election of a majority Conservative government means that the Parliamentary boundary review will presumably go ahead on the rules passed under the last government, but delayed by the Liberal Democrats (the review that was started in the last Parliament was abandoned before it was completed after the law was changed). There is no need for the government to pass any laws to implement this, it will start up automatically early next year once electorate numbers are available, though Parliament will still have to vote to implement the Boundary Commissions’ recommendations, and with a small majority that is not necessarily a given – last time round there were a couple of Tory MPs who said they were going to vote against the new boundaries, and the government doesn’t have much of a majority to begin with.
Anyway, a couple of people have asked me how this election would have looked had the revised boundaries proposed in the last Parliament gone through. I’ve done a rough rejig of my provisional boundary calculations using the result of this election, and had the new boundaries gone through the Conservatives would have won 322 seats, nine fewer than they did but enough to give them a healthy majority of 44 in a Commons of 600 MPs. Labour would have won 204 MPs (28 fewer), the SNP 50 seats (and would have pushed Labour out of Scotland entirely) and the Lib Dems just 4.
Of course, this is not necessarily a good guide to what the new review this Parliament will produce – electorate numbers will have changed since 2010 and given some of the discussion after the abandoned review I suspect the English Commission may be a little more open to splitting wards so the proposed changes are less disruptive (something that requires only a change of mindset, not a change of rules!), but we shall see.
