Democratic presidential candidate Hillary Clinton held a six-point lead over Republican rival Donald Trump, according to a Reuters/Ipsos poll with new wording that was released on Friday, the day after she formally accepted her party's nomination for November's election.

Nearly 41 per cent of likely voters favour Clinton, 35 per cent favour Trump, and 25 per cent picked "Other," according to the new July 25-29 online poll of 1,043 likely voters, which overlapped with the Democratic National Convention in Philadelphia.
