The bookie is now offering 11/4 on Trump to become president, shortening from 3/1.
However, Clinton still remains the frontrunner. She is ahead with pollsters and bookies alike, and leading Trump in several key battleground states.
Last week, introduced by Trump as “the man behind Brexit” - despite the fact Farage held no role with the official Brexit campaign Vote Leave – the Ukip leader told a rapturous crowd he was bringing a message of “hope and optimism”.
The Ukip leader said: “You have a fantastic opportunity here with this campaign. You can go out, you can beat the pollsters, you can beat the commentators, you can beat Washington. And you'll do it by doing what we did for Brexit in Britain.”
