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.
The result makes Mr Trump the first one-term president since the 1990s.
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.
The election has seen the highest turnout since 1900. Mr Biden has won more than 73 million votes so far, the most ever for a US presidential candidate. Mr Trump has drawn almost 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.
His campaign has filed a barrage of lawsuits in various states and earlier on Friday, as Mr Biden appeared on the cusp of victory, said: “This election is not over.”
The election was fought as coronavirus cases and deaths continued to rise across the United States, with President Trump arguing a Biden presidency would result in lockdowns and economic gloom. Joe Biden accused the president of failing to impose sufficient measures to control the spread of Covid-19.
Joe Biden is now set to return to the White House, where he served for eight years as President Barack Obama’s deputy. At the age of 78, he will be the oldest president in American history, a record previously held by the man he has now defeated, Donald Trump, who is 74.
Joe Biden’s projected victory after four days of painstaking vote-counting is the denouement of an extraordinary campaign, conducted during a devastating pandemic and widespread social unrest, and against a most unconventional of incumbents.
In his third try for the presidency, Mr Biden found a way to navigate the political obstacles and claim a win that, while perhaps narrow in the electoral college tally, is projected to surpass Mr Trump’s overall national total by at least four million votes.
With his projected victory, Joe Biden becomes the oldest man ever elected to the White House. He brings with him the first woman vice-president, whose multi-ethnic heritage carries with it numerous other firsts.
Mr Biden can now begin the arduous task of planning the transition to his new administration. He will have just under three months to assemble a cabinet, determine policy priorities and prepare to govern a nation facing numerous crises and sharply divided along partisan lines.
Joe Biden has been dreaming of the White House for most of his 50 years in the public arena. With this prize of a lifetime, however, come the challenges of a lifetime.
