BBC: Mitt Romney has declared victory in Nevada's Republican caucuses, cementing his frontrunner status in the race to be the party's presidential candidate.
With just over 70% of the votes counted, he had secured 47.6% of the vote - well ahead of his nearest rival Newt Gingrich on 22.6%.
It is Mr Romney's second victory in a week, following his success in Florida.
Mr Gingrich - a former house speaker - has vowed to fight on until the party's convention in August.
"I'm not going to withdraw," he said. "I'm actually pretty happy with where we are, and I think the contrast between Governor Romney and me is going to get wider and wider and clearer and clearer over the next few weeks."
Earlier, Mr Gingrich said he expected Mr Romney to win in Nevada, partly due to the state's high Mormon population. Mr Romney is a Mormon.
Mr Romney won Nevada in his previous bid to be the Republican presidential candidate in 2008. (+ video) » | Sunday, February 05, 2012
