Former US president Obama has been urged to "step in" after there have been fresh calls for Joe Biden to step down following his debate last week.
Biden has been heavily criticised for his performance when he went head-to-head with Donald Trump ahead of November's US election.
After the "car crash" debate, Obama rushed to the defence of the US president and said that "bad debates happen."
However, former Head of Press for the Prime Minister Giles Kenningham revealed that he believes now is the time for Obama to "step in."

Speaking to Camilla Tominey on GB News, Kenningham said: "It was an absolute car crash by any stretch of the imagination.
"We are in a situation now where Obama needs to step in, put his hand on his shoulder and say Joe look."

He added: "Not Jill Biden because she's too closely aligned to this.
"Democrat grandees need to step in and there are candidates ready to go.
"You've got Gavin Newsom, the governor of California who is someone out of central casting but looks the part. If you're going to do it, do it. If you're Trump, you definitely want Biden to stay in."
Hillary Clinton also shared support for Biden but noticeably did not mention the debate.

She wrote on social media: "The choice in this election remains very simple.
"It's a choice between someone who cares about you—your rights, your prospects, your future—versus someone who's only in it for himself.
"I'll be voting Biden."
Following the debate, the president himself admitted his performance was poor.
Biden struggled during the debateCNNHe told a crowd at a rally in North Carolina on Friday: "I don't debate as well as I used to but I can do this job".
Biden appeared to freeze during the debate and had difficulty stringing together strong cohesive statements.
CNN Chief National Correspondent John King said Democrats have declared "we have a problem" in private circles.
