John Mann, who sits on the influential Treasury Select Committee, has hit out at his Party leader, arguing Mr Corbyn’s age means he cannot be the next Prime Minister of the UK.
The Bassetlaw MP and staunch Brexiteer has been on a collision course with the Labour leadership since Mr Corbyn took control of the party.
He previously had a high profile run-in with Ken Livingston, an ally of Mr Corbyn, calling the former London Mayor a “Nazi sympathiser”.
His latest controversy came in an interview with the Blairite commentator Richard Angell as he accused his leader of being too old to lead the country.
The MP said: “I think the next election will be in 2022, by which stage Jeremy Corbyn will be 73 and facing the prospect of being Prime Minister at 78.”
If he oversaw a full term as Leader of the UK, the next General Election would not be until 2027, by which time Mr Corbyn would be 78.
Despite the age of the opposition leader, if Labour won an election in 2022, the Islington North MP would not be the oldest person to enter Downing Street.
William Ewart Gladstone was appointed Prime Minister at the age of 82 when he was appointed to the position in 1892.
Mr Mann added: “I have no intention of being an MP in my 70s, never mind anything more than that.
“So I don’t think Corbyn will be Prime Minister.
“I think there will be a new leader of the Labour party by the next General Election.”
The Labour MP also went on to indicate who he thought should replace the current leader of the party when he steps down.
In his interview with Mr Angell the Bassetlaw MP said the next leader of the party should be a woman.
He said: “I don’t know who it will be but I think it will be a woman – and it should be a woman.”
The Labour party has never been led by a female before.
Following a leadership challenge on Mr Corbyn in 2016, Angela Eagle put herself forward as a potential successor for the role.
However, her campaign was mocked for the bright pink backdrop used for her campaign and was accused by some of looking like she was going to launch a new women’s fragrance rather than a leadership bid.
One person joked on Twitter at the time: “The pink banners at Angela Eagle’s launch make it look like her campaign is sponsored by Rimmel London.”
Ms Eagle dropped out of the leadership election just one week later.
