Washington, US (BBN)-Donald Trump has won the Republican presidential primary in New York while Hillary Clinton has triumphed in the Democratic race.
With the majority of votes counted, Mr Trump looks set to extend his lead over rivals Ted Cruz and John Kasich, reports BBC.
Meanwhile Democratic hopeful Mrs Clinton, a former senator for New York, is on course for a victory over Brooklyn-born Bernie Sanders.
Wins will put Mrs Clinton and Mr Trump closer to securing their nominations.
With more than 98 per cent of the results in, Mr Trump is leading with just over 60 per cent of the vote while Mrs Clinton has just under 58 per cent.
US networks projected that Mr Trump had won in his home state barely seconds after the polls closed at 21:00 EDT (01:00 GMT).
Speaking at Trump Tower in Manhattan, he said: “I have to say to the people that know me the best – the people of New York – when they give us this kind of a vote it’s just incredible.”
He said he was going to get more delegates than “anyone projected even in their wildest imaginations”.
The big question is whether the billionaire businessman will make a clean sweep of all 95 Republican delegates at stake in New York by earning the majority of votes.
This would reduce the chances of a contested nomination at the Republican party convention in July.
Claiming her win, Mrs Clinton told supporters her campaign for the nomination was “in the home stretch and victory is in sight”.
“New Yorkers, you’ve always had my back and I’ve always tried to have yours,” she said. “Today together we did it again and I am deeply, deeply grateful.”
It has been a fierce campaign in the state, with the leading candidates using their local ties to attract voters.
The Democratic campaign has turned increasingly negative, with Mrs Clinton and Mr Sanders trading barbs about their qualifications.
But following the latest result in the race for the Democratic nomination, Mrs Clinton said there was “much more that unites us than divides us”.
US media reaction
Donald Trump’s win will shift the momentum away from the anti-Trump movement and back to the brash businessman, the New York Daily News says
In her home state, Hillary Clinton seemed relaxed for the first time in a “rocky and unpredictable Democratic race,” according to the New York Times
A series of distractions in the lead-up to the New York vote meant Bernie Sanders never came close to pulling off the upset victory he had predicted, Politico says
Republican contender John Kasich’s second-place showing in New York bolsters his argument that he – rather than Ted Cruz – would be most likely to beat Donald Trump in a contested convention, the Washington Post argues
Meanwhile Mr Sanders, who has vowed to fight on in the nomination process, spent Tuesday in Pennsylvania before heading home to Vermont for a day off the campaign trail.
Republican hopeful Mr Cruz, whose criticism of “New York values” attracted scorn in the state, had also moved onto Pennsylvania and dismissed the New York result as nothing more than “a politician winning his home state”, according to the Associated Press.
Pennsylvania is the most important of five states holding both Republican and Democratic primaries on 26 April, and then candidates will look to score successes in Indiana on 3 May.
