In the United States, presidential election is being held on Tuesday.
The incumbent President Donald Trump is a candidate of the Republican Party while Joe Biden is contesting the election on Democratic Party ticket.
The Democratic candidate maintains a solid national lead in the polls but this advantage is narrower in key states which could decide the result.
More than 90 million people have already cast their ballots in early voting, putting the country on course for its highest turnout in a century.
