Labour got 262 seats out of the 650 in Parliament, on the basis of 40% of votes cast nationally. 40% of 650 seats is 260, so the actual result is a fair approximation, this time.
But although the Conservatives polled 42.4%, which proportionally should have given them 276 seats, actually they got 318 = 42 bonus Members of Parliament!
So now they're getting back into bed with Ulster Protestants to make a workable coalition. What effect that will have in Northern Irish politics, who knows.
The system doesn't even work within individual constituencies, as I discussed six years ago*. In the 2005 General Election, only 220 MPs out of 650 obtained a majority of votes cast by their constituents; in 2010, only 217.
I expect it will turn out to be a similar picture when the results of this fiasco become available.
No wonder the inhabitants of The Bubble hate plebiscites like the EU Referendum; they're so used to gaming the usual rotten setup.
