DONALD Trump has declared an unsupported victory in the US election, with millions of ballots still to be counted.

Speaking during a tense night in which the electoral college votes got down to the wire with no clear winner in sight, the Republican candidate insisted he will go to the Supreme Court to fight the results.

With millions of votes still be counted, he told supporters: “Frankly we did win this election."

Without evidence, he added: “This is a fraud on the American public, this is an embarrassment to our country.

“So our goal now is to ensure the integrity for the good of this nation. This is a very big moment.

“This is a major fraud on our nation.

“We want the law to be used in a proper manner. So we will be going to the US Supreme Court, we want all voting to stop.”

Results are showing there is a tight race in the key battlegrounds of Pennsylvania, Michigan, Iowa and Wisconsin.

At the time of writing the results are pretty much neck and neck – 40 out of 50 states have been declared with Biden on 220 electoral college votes and Trump on 213. 270 are needed to win the presidency.

This morning Democratic challenger Joe Biden said he believes he is “on track” for a victory, pointing towards projections of a possible Arizona win. It would be the first time a Democrat has claimed the state since Bill Clinton in 1998.

The final result is not likely to be clear until later today or possibly later this week.

Speaking to Sky News this morning, Foreign Secretary Dominic Raab said he was confident in the “checks and balances” in the US system as he said the presidential election was “too close to call”.

He told viewers: “We’ll see how this plays out, I think it could be a very close race.

“We may not get a definitive result for hours, if not days.

“But we are totally confident the American system has the checks and balances to give us a definitive result and we will wait and see.

“Of course, the UK-US relationship is in great shape and we are confident that it will go from strength to strength whichever candidate wins the election.”

Meanwhile First Minister Nicola Sturgeon commented on the results so far and Trump's false victory claim, telling Twitter: "Crucial hours and days ahead for the integrity of US democracy. Let’s hope we start to hear the voices of Republicans who understand the importance of that."
