Betting support for odds-on favourite Hillary Clinton has 'virtually dried up'

In addition, following the news that the FBI has found new emails that may be related to its investigation into Ms Clinton's use of a private email server when she was secretary of state, William Hill have slashed the odds on rival Donald Trump winning the race to the White House.

At time of writing, Clinton's odds are out to 2/7 (a 77% chance of winning the election) from 1/9 (90%) just one week ago, while Trump's odds have shortened from 11/2 (a 15% chance of winning) to 11/4 (26%).

William Hill spokesman Graham Sharpe told BetOnPolitics.co.uk: "For the last week Trump's odds have been edging downwards, and the recent FBI news has accelerated the process.

"No one will touch Clinton, despite odds which just a week ago would have caused a stampede to get on!"

Sharpe added: "'Throughout the campaign, Clinton has attracted the heftier bets, but Trump has accounted for two thirds of all the indivudual bets placed - that percentage has certainly risen during the last 48 hours. And those stats are very similar to those recorded by us during the EU Referendum when the odds Remain was odds-on favourite, despite a large majority of the individual bets being placed on Leave, the apparent outsider.

"Maybe betting history is about to repeat itself."

Recent developments have also led to the bookmaker lengthening their odds for Clinton to win both this and the next Election in 2020 from 2/1 to 9/4, while Trump's odds of doing likewise have been cut from 12/1 to 10/1.
