Lots of interesting ins and outs with that election. No one thought that any single party would get a majority.
All of the heads of the other major parties resigned, UKIP, Labour, and Lib Dems, which is fairly common after a loss in a parliamentary system.
Labour was gutted in Scotland by the nationalists. Scotland has always been a Labour stronghold as the Scots are very left leaning. Labour had been ultra vocal about keeping Scotland from going independent.
The Liberal Dems(left-center) were supposed to be ascendant five years ago and they got gutted.
UKIP(anti-EU), although it didn't win a bunch of seats, placed second in a huge amount of races.
The Conservatives should have had a slam dunk as things are purring along nicely in GB, and while things ended up that way, "change" seemed to be in the air.
I think GB will see some massive upheaval over the next ten years.
