Voters are heading to polling stations across the US today to pick their next president in a once-in-a-lifetime election.
In the red corner, Donald Trump is hoping to repeat his victories in the states that he took from Hilary Clinton in 2016. In the blue corner, Joe Biden has gone all out to woo back the voters that left the party four years ago.
The final result is expected to come down to a few key swing states that the victor will need to build a winning coalition. So what potential early indicators of who is going to win should you be looking out for as the results come in?
Ones to watch
Owing to the electoral college system, the results in a total of just eight of the 50 US states are likely to determine who takes the keys to the White House.
