In pictures: As we await the results… Let’s take a look back at how election day unfolded in the US

America’s ugly and unpredictable presidential election entered its final hours on Tuesday, with voters flocking to polls to choose between Democrat Hillary Clinton, hoping to become the first woman to serve as commander in chief, and Republican Donald Trump, the billionaire businessman who tapped into a searing strain of economic populism.

Mrs Clinton appeared to have multiple paths to triumph, while Mr Trump needed to prevail in most of the battleground states to secure an upset. Control of the Senate was also at stake, with Democrats needing to net four seats if Mrs Clinton wins the White House.

As the result of the vote looms, we take a look back at how election day unfolded across the US in pictures.
