The BBC has a nice chart which summarizes Thursday's election results in the U.K. The Conservatives won 331 seats, out of a total of 650. This clear majority obviates the need for coalition partners; all ministerial posts will be filled with Tories.
The Labour Party won 232 seats, Scottish National Party 56, the Liberal Democrats won 8, as did the Democratic Union Party of Northern Ireland. Several other parties won 4 or fewer, for a total of 15 in a category best thought of as "other."
A peculiarity of the U.K.'s system is that the SNP which received 1.4 million votes won 56 seats while the UK Independence Party received 3.8 million votes and won 1 seat. The reason: SNP voters are geographically concentrated in Scotland, UKIP voters are scattered.
