Billionaire Donald Trump has won the Republican primary in South Carolina with nearly 33% of the vote.

The race for second between Ted Cruz and Marco Rubio was extremely close to call.

Jeb Bush pulled out of the race after a disappointing contest where he came third from last with only John Kasich and Ben Carson pulling in less votes.

The top three results from the South Carolina primary, with 98.8% of the votes counted, are below:

Meanwhile Hillary Clinton narrowly won the Democratic Nevada caucuses on Saturday, beating back a stronger-than-expected challenge from her rival for the Presidential nomination Bernie Sanders.

Clinton was leading with 52.2% of the vote to Sanders' 47.8% with 65% of the precincts reporting.

Television networks Fox News and MSNBC projected Clinton would win, however vote counting was delayed in Nevada by heavy turnout.

Hillary Clinton's narrow margin of victory in a state where she was once expected to win by double digits suggested the Democratic nominating race could be long and hard-fought, with Bernie Sanders performing strongly in a state with a heavy minority population.

After routing Clinton in New Hampshire and finishing a strong second in Iowa - states with nearly all-white populations - Nevada gave Sanders his first chance to prove he can win over black and Hispanic voters and compete nationally as the race moves to states with more diverse populations.
