Donald Trump has won the South Carolina primary in the Republican race for president, cementing his status as the man to beat for his party’s nomination.
In the Democratic contest, Hillary Clinton beat Vermont Senator Bernie Sanders in a tight race in Nevada.
Both results will be key ahead of the “Super Tuesday” round on March 1, when a dozen more states make their choice.
The Trump victory claimed a major scalp when former Florida Governor Jeb Bush dropped out of the race.
He finished a distant fourth, days after his brother, former President George W Bush, made a rare political appearance to boost his flagging campaign.
Republican senators Ted Cruz and Marco Rubio were locked in a battle for second place in the state.
