Former Vice President Joe Biden has a 13-point lead over incumbent President Donald Trump ahead of November’s election, according to a new national poll.

The Democratic presidential candidate’s lead, with 48 percent of those asked backing Biden and 35 Trump, is his biggest yet recorded by Reuters/Ipsos.

It coincided with the poll showing the lowest approval rating for Trump since November, with 57 percent disapproving of his performance as president and 38 approving.

The Reuters/Ipsos poll was conducted online with respondents throughout the U.S. between June 10 and 16.

Responses were garnered from 4,426 American adults, with 2,047 Democrats and 1,593 Republicans among them, while the poll had a credibility interval of plus or minus 2 percent.

Polling has largely given Biden the lead in recent months, with Real Clear Politics’ average ahead of the Reuters/Ipsos poll giving him an advantage of 8.1 points.

A poll from CNN last month gave Biden a slightly greater lead than the Reuters/Ipsos survey, at 14 percent.

In this, 1,125 registered voters were asked who they would vote for, between June 2 and 5, with 55 percent stating Biden and 41 Trump. The poll, conducted by SSRS for CNN, had a margin of error of plus or minus 3.4 percent.

Recent state-specific polling has also seen Biden garner leads, with an advantage growing in Michigan, Florida and Arizona.

As previously reported by Newsweek, Biden has also taken the lead in polls from several battleground states.

Newsweek has contacted the Trump and Biden campaigns for comment.

Biden’s lead over Trump comes as the president looks to return to physical campaigning, with a rally scheduled for Tulsa on Saturday.

The event is to be held in a venue with a 19,000 capacity, with talks that it could be expanded or shifted to another venue due to ticket demand.

It will be the president’s first in-person rally since March, with such events being stalled due to the COVID-19 outbreak. The Trump campaign has also released a statement urging Biden to return to in-person events.

“This is obviously a tactic to help [Biden] avoid errors and embarrassing, lost trains of thought, while also conveniently preventing the press corps from asking him any questions in person,” wrote Trump 2020 Communications Director Tim Murtaugh in a statement.

“At what point will Biden subject himself to the scrutiny American voters deserve when considering the next President of the United States?”

Concerns over the safety of such a rally as that in Tulsa have been raised, with officials worried it might lead to a spread in coronavirus cases.

This criticism comes amid general declining approval figures of Trump’s handling of the pandemic, with the Reuters/Ipsos poll finding 55 percent disapproved and 40 percent approved.

The president’s general disapproval rating has also declined in recent polling, with the level dropping further amid widespread protests following the death of George Floyd.

As well as holding an overall lead, polls have seen Biden ahead on most key points, as previously reported by Newsweek.

He has been ahead in regards to who voters believe would best deal with the coronavirus pandemic, race relations and on dealings with China.
