The polls have swung again as Hillary Clinton and Donald Trump tour swing states in the final days of the presidential race. Ms Clinton is currently ahead in the polls, after Mr Trump briefly overtook her, with just four days to go until election day.

The Democrat politician has a 6.1 per cent lead over rival Donald Trump. 48.9 per cent of voters say they are backing Ms Clinton, compared to 42.8 per cent who are backing her Republican rival.

The figures have been released by TrumpxClinton, an election tracker which takes a rolling average of all major polls.

Both politicians are touring so-called 'swing states' which commentators believe will make or break the campaigns, depending on who succeeds in wooing undecided voters.

Mr Trump enjoyed a recent surge of support among voters, after it was reported the FBI is investigating Ms Clinton in relation to allegations surrounding her connection to emails sent via a private server.

A poll for ABC News and the Washington Post put Mr Trump ahead by the smallest of margins- 46 per cent to Ms Clinton’s 45 per cent. Stock markets responded to the news, with shares in Asia hitting a seven-week low following losses on Wall Street. FXTM Chief Market Strategist Hussein Sayed said he believed the markets were in the “early stages of panic” about the impending election.

Ms Clinton’s campaign team questioned the methodology of the poll, suggesting it may not have been accurate. The Democrat appears to have since regained ground, with a welcome boost just days before Americans head to the polls.

Statisticians at Predict Wise now estimate Mr Trump has a 17 per cent chance of becoming President.

Election day on Tuesday 8 November will bring to an end one of the most divisive and dramatic elections in US history. Mr Trump has suggested he may not accept the result if Ms Clinton wins, indicating he feels the election may be rigged.
