So they went ahead and had those elections in the UK, as you may have heard. The result was a major victory for primary colors, as this Wikipedia map shows. (Blue = Conservatives; Red = Labour; Yellow = LD; assorted = regional and minor parties):
The political parties, however, didn't do so hot. Oddly, though electoral politics is supposedly a zero-sum game, all three major parties managed to lose. The Tories fell short of the majority they were hoping for; Labour lost a ton of seats and had their worst showing in decades; and the Lib Dems, despite anticipation of major gains and predictions that they might crack 100 seats, actually lost a handful of seats. The Tories now have 305 seats, to Labour's 258, and the Lib Dems' 57, with the rest distribute amongst various regional parties and a Green. With ~323 needed to form a majority, the parliament is, as they say, hung.
For comparison, this is what the map looked like after the last election, in ought-five:
