America Decides: Hillary Clinton In early Lead?

Most of the latest polls show Hillary Clinton has a narrow lead, but the night promises to be a tense affair as more than 120 million Americans are expected to vote - and all outcomes possible.

Counting in many of America's 50 states will begin at about midnight tonight, and by about 4am tomorrow either Hillary Clinton or Donald Trump could be elected the next President of the United States.

In order to win the election, a candidate must secure 270 out of the 538 votes in the electoral college.

The first results are announced in Dixville Notch, New Hampshire, which has already been won by Hillary Clinton by 4 votes to 2.
