WASHINGTON (Reuters) - Democratic presidential candidate Joe Biden's lead over President Donald Trump in Michigan is looking increasingly comfortable but the two remain neck and neck in North Carolina, Reuters/Ipsos opinion polls showed on Tuesday.

Reuters/Ipsos is polling likely voters in six states - Wisconsin, Pennsylvania, Michigan, North Carolina, Florida and Arizona - that will play critical roles in deciding whether Trump wins a second term in office or if Biden ousts him.

A week before the Nov. 3 election, Biden leads Trump nationally by 10 percentage points, according to the Reuters/Ipsos poll. The national online survey, conducted Oct. 23 to 27, found that 52% of likely voters said they were backing Biden, while 42% were voting for Trump.

Five percent said they were considering a third-party candidate and only 2% said they did not know yet how they would vote. Nearly one-third of American adults said they had already voted. Biden led by 8 points in the previous national poll conducted Oct. 20 to 22.
