LIVE Super Tuesday Results FULL Fox News Coverage - Donald Trump FULL Victory Speech after winning Illinois, NC & FL on March 15th Super Tuesday
Five US states are holding primary elections for November's presidential poll, in a crucial round that could give Democratic and Republican front-runners a chance to cement their leads.
Polls have opened in Ohio and Florida - both deemed key states - as well as in North Carolina, Illinois and Missouri.
Democratic front-runner Hillary Clinton is hoping to fend off her resurgent challenger, Bernie Sanders.
Meanwhile Donald Trump will aim to edge out his rivals in the Republican race.
The New York real estate mogul is the favourite to win his party's nomination but has run into fierce opposition from within the Republican establishment, as well as facing condemnation from the Democrats.
He scored an early success on Tuesday when he secured all nine delegates in the Northern Mariana Islands, part of the US Pacific Commonwealth, after winning almost 73% of the Republican caucus there.
