Nevada Republicans favour Mitt Romney

Mitt Romney has won Nevada's Republican caucuses, early results from the western US state suggest.

Voting in most areas finished early on Saturday evening, but Clark County, which includes Las Vegas, held an evening caucus to allow observant Jews to participate.

Returns from 13 of 17 counties showed Romney had more than 40%. He later declared victory.

Alastair Leithead has been following events from Los Angeles.
