BREAKING NEWS: Joe Biden Beats Donald Trump To Win US Presidential Election

Joe Biden has won the race to become the next US president, defeating Donald Trump following a cliff-hanger vote count after Tuesday's election.

The BBC projects that Mr Biden has won the key battleground of Pennsylvania, propelling him over the 270 electoral college vote threshold required to clinch the White House.

The Trump campaign has indicated their candidate does not plan to concede.

Mr Biden said it was now time for America to "unite and heal".

"With the campaign over, it's time to put the anger and the harsh rhetoric behind us and come together as a nation," he said.

He said he was "honoured and humbled" to be elected and said the record turnout in the face of "unprecedented obstacles" showed that democracy "beats deep in the heart of America".

The result makes Mr Trump the first one-term president since the 1990s.

Mr Biden's running mate, Kamala Harris, is set to become the first woman vice-president.

The BBC's projection of Mr Biden's victory is based on the unofficial results from states that have already finished counting their votes, and the expected results from states like Wisconsin where the count is continuing.

His projected win in Pennsylvania takes him to 273 electoral college votes.

The election has seen the highest turnout since 1900. Mr Biden has won more than 74 million votes so far, the most ever for a US presidential candidate. Mr Trump has drawn more than 70 million, the second-highest tally in history.

President Trump had falsely declared himself the winner of the election when vote counting was unfinished. He has since alleged irregularities in counting, but has not presented any evidence of election fraud.

After Mr Biden was projected to win he remained defiant, saying Mr Biden was "falsely posing as the winner" and insisting the election was "far from over".

His campaign has filed a barrage of lawsuits in various states.
