Joe Biden closes in on the US presidency as he takes the lead in key battleground states
Joe Biden has taken the lead in the key battleground states of Pennsylvania and Georgia.
As it stands, the Democratic candidate now leads Trump in Pennsylvania by 5,587 votes, in Georgia by 1,097 votes, in Nevada by 11,438 votes and in Arizona by 47,052 votes.
Biden currently has 253 electoral college votes while Donald Trump has 214 electoral college votes. The candidate who reaches 270 votes wins.
Donald Trump held a comfortable lead in both states, but mail-in ballots and absentee votes in urban hubs, such as Atlanta in Georgia and Philadelphia in Pennsylvania, have swung the race in Biden's favour.
Mr Trump needs to win Pennsylvania if he is to win the presidency. The state was a key battleground state which Mr Trump won from the Democrats in 2016, while Georgia has been a Republican stronghold at every presidential election since 1996.
Military votes in Georgia still need to be added, but with 99% of the vote counted, Biden is now the firm favourite to become the 46th president of the US.
Counting is also still ongoing in Arizona and Nevada, two states where Biden is extending his lead.
