Donald Trump has vowed to be a 'president for all Americans' after pulling off the biggest upset in US presidential history.

The Republican candidate claimed a shock win in the US election after securing key swing states including Florida, Georgia, Ohio and North Carolina.

Mr Trump’s victory was confirmed after the result for Wisconsin was announced. The state voted for Mr Trump, giving him the electoral votes he needed to clinch the White House.

Polls had indicated that Hillary Clinton was on course to win the election, however, Mr Trump’s ‘Make America Great Again’ message appears to have gone down better with US voters.

Taking to the stage at a victory rally in New York, Mr Trump promised to "make America great again", telling supporters that it was "now time for America to bind the wounds of division and come together".

He said: "It's been what they call a historic event - but to be a really historic we have to do a great job.

"I promise you I will not let you down, we will do a great job - I look very much forward to being your president.

"And hopefully at the end of two years, or three years, or four years - or maybe even eight years - you will say that so many of you worked so hard, but you will say that was something that you were really very proud to do."

He added: "I can only say that while the campaign is over, our work on this movement is only now just beginning.

"We're going to get to work immediately for the American people and we are going to be doing a job that hopefully you will be so proud of your president.

"It's my honour, it's been an amazing evening. I love this country."

Mr Trump had campaigned on a promise to "drain the swamp" in Washington, with Mrs Clinton's use of a private email server while secretary of state and the 2012 attack on the US diplomatic compound in Benghazi, Libya, frequently highlighted during his campaign against the rival he dubbed "crooked Hillary".

The first states to be decided produced the predicted results - Kentucky, Indiana, Oklahoma, West Virginia, South Carolina and Tennessee went for Mr Trump, while Vermont, Massachusetts, Maryland, New Jersey, Delaware and the District of Columbia were claimed by Mrs Clinton.

In later waves, Mr Trump added Texas, Kansas, Georgia and more to his column while Mrs Clinton took New York and Illinois. She later added huge and reliably Democratic California.

Michigan and Wisconsin, two Midwestern powerhouses that have not voted for a Republican presidential candidate since the 1980s, took on unexpected importance.

Mrs Clinton's campaign had largely taken both for granted, but made a late push in Michigan in the race's final days.

The Democratic candidate thanked her team for their support “whatever happens tonight” on Twitter as the results for key swing states were announced.

Mr Trump's victory sent Dow Jones futures and Asian markets tumbling, reflecting investor concern over what his presidency might mean for the economy and trade.

The Republican's outspoken rhetoric about Mexicans during the campaign - and his promise to build a wall between the US and its southern neighbour - also triggered a fall in the peso.

Mr Trump’s bid for the White House appeared to have suffered a setback last month after his campaign was rocked by allegations of sexual assault, which he denies. Ms Clinton’s campaign was also hit after the FBI announced an investigation into the Democratic candidate’s private emails. The FBI said earlier this week that the investigation had found no evidence of criminality.

Mr Trump’s supporters celebrated his win an election night event in New York.

The 45th US President will be inaugurated in January 2017.
