Donald Trump is refusing to go quietly as he tweeted defiantly from the White House - doubling down on his election rigging claims - moments after Joe Biden told the nation he would win.  Follow our live updates.

We are on the cusp of an election result, with Mr Biden taking the lead in the one remaining state he needs to reach 270 electoral votes.

In his late-night speech, he said the votes were telling a "clear and convincing story".

"We don't have a final declaration of victory yet but the numbers tell us it is clear, and a clear and convincing story," he said. "We're going to win this race. Just look at what has happened since yesterday.

"24 hours ago, we were behind in Georgia, now we are ahead and we're going to win that 24 hours ago, we were behind in Pennsylvania and we are going to win Pennsylvania."

He also addressed Mr Trump's claims.

"Your vote will be counted. I don't care how hard people try to stop it. I will not let it happen. People will be heard," he said.

Pennsylvania, and its 20 electoral votes, will be enough to win the election for Mr Biden. As things stand, Mr Biden leads by 28,833 votes there, having once trailed by 700,000, before officials started to count the mail-in vote.

Now, with about 100,000 ballots left - many of them from heavily Democratic areas - he seems all but certain to win. We still have to wait and see, though.

Mr Biden has also inched in front in Georgia. He is up by a tiny margin of 7248 votes there, with very few left to count. He is probably going to win the state, but don't expect the TV networks to project it anytime soon, given how close it is. And the state government has already announced there will be a recount.

Three other states remain contested. Mr Biden leads in Nevada and seems all but certain to win it, as most of the outstanding votes are from Democrat-leaning Clark County. The President leads in North Carolina, and should hold on, though we probably won't know for certain until next week.

And then there's Arizona. Fox News and The Associated Press both called it for Mr Biden days ago. Other networks haven't, and the Trump campaign has insisted it will end up winning the state. It's certainly a close contest, and we will keep watching it, though the latest batch of votes suggests Mr Trump is not catching up fast enough to overtake Mr Biden there.
