(BBC) – Former US vice-president Joe Biden appears to have been handed a major boost in the Democratic race to take on Donald Trump in November’s election.
Mr Biden is projected to win South Carolina’s primary, according to US media. Voters there have been picking who they want to be the Democratic nominee for the White House.
Left-winger Bernie Sanders is likely to remain in the lead overall.
Another 14 states vote on Super Tuesday this week.
By the end of Super Tuesday, it could become much clearer who the nominee will be. South Carolina is only the fourth state to have voted so far in the months-long primary season.
What happened in South Carolina?
With almost a third of votes counted, Mr Biden has 51% of the share, ahead of Mr Sanders and billionaire hedge-fund manager Tom Steyer.
Mr Biden had been pinning his hopes on a strong result in the southern state, after performing poorly in Iowa, New Hampshire and Nevada. He regularly cited his strong support among African-Americans, and polls suggest an endorsement by influential black congressman James Clyburn played a significant part in how people voted.
