US election 2020: What's happening in remaining key states

There are now just a handful of states up for grabs to determine the final outcome of the election.

Biden currently has 243 electoral college votes, and Trump 214. They need 270 to win the White House.

The key remaining states are Arizona, Georgia, Nevada, Pennsylvania, North Carolina and Wisconsin.

There are various possible paths to victory.

To reach 270, Trump could lose Wisconsin, but he must win Georgia (16 votes), North Carolina (15), Pennsylvania (20), and either Arizona (11) or Nevada (6) to prevail.

Biden could win without Pennsylvania (where a projected result is not expected any time soon), but he would need to win Arizona, Georgia and Nevada.

Note that some news outlets have projected a Biden win in Wisconsin and Arizona, but the BBC - via our monitoring partners - has deemed them too early to call.

Counting is continuing, with officials expected to provide updates later in the day.

In Georgia, officials said they would keep counting all night until all the ballots are tallied. Trump's lead there is slowly dwindling, down to 24,000 votes, the New York Times reports

In Nevada, the race is on a knife edge, and Biden leads by fewer than 8,000 votes. Officials said the next results would be posted on Thursday at 17:00 GMT (09:00 local time)

In Pennsylvania, Trump's significant lead has narrowed. With 90% of ballots counted at 05:45 GMT (23:30 Wednesday local time), Trump was ahead by 164,414 votes

In Arizona, Biden was leading by about 80,000 votes, with further results expected on Thursday

In North Carolina, where most of the votes have been counted but some remaining to be tallied, Trump clung to a narrow lead with some 77,000 votes

Our partners, Reuters, have still not projected Wisconsin, where Joe Biden's lead is said to be of more than 20,000 votes. But other news outlets are reporting that Biden has won the state.
