The Conservative Party has won the UK general election, winning more votes than any other party and more seats than any other party. David Cameron has not won a majority, and as a result the incumbent Prime Minister has a right to try to form a government.
He can do this by forming a formal coalition with the Liberal Democrats or by seeking agreements with parties on an ad-hoc basis as a minority government.
If the Prime Minister cannot form a government, David Cameron could take the same options.
It is thought likely he will seek to form a minority government.
The Liberal Democrats have taken some heavy losses. Their breakthrough, widely predicted, has not happened.
