Donald Trump has emerged the decisive winner of Nevada's Republican caucuses, leaving his main rivals battling for second place in an increasingly urgent effort to slam the brakes on the billionaire businessman's juggernaut.

Mr Trump now has three straight victories - in the West, the South and North east - a testament to his broad appeal among the "mad-as-hell" voters making their voices heard in the 2016 US presidential race.
