Republican Donald Trump has conceded defeat to Ted Cruz in Iowa’s presidential nominating contest, while Democrat Hillary Clinton is locked in a tight race against Bernie Sanders, according to a Sky news report.
Mr Cruz, a conservative US senator from Texas, led the billionaire businessman by 27.7% to 24.4%, with 90% of precincts reporting results in the Midwestern US state.
Florida Senator Marco Rubio, viewed by many Republicans as a more mainstream alternative, was nipping at Mr Trump’s heels in third place at 23%.
Mrs Clinton, a former Secretary of State, held a lead of 49.8% compared to 49.6% for Mr Sanders, a US senator from Vermont, with 90% of precincts reporting in that race.
Mr Trump told supporters: “We finished second and I just want to say, I’m really honoured and I want to congratulate Ted.”
But in typically bullish style, he predicted he would still win the Republican nomination.
The third Democratic candidate, Martin O’Malley, has suspended his campaign after trailing badly. He has gained less than 1% of Iowa’s votes.
Republican Mike Huckabee has also dropped out of the race.
