The leader of the opposition Jeremy Corbyn has refuted claims he called the Prime Minister a “stupid woman” at the last Prime Minister’s Questions of the year.

Prime Minister May was lambasting the Labour leader for the confusion over his decision to table a motion of no confidence against her: “They said they’d put down a vote of no confidence, then they said they wouldn’t.

“Then they said they would, then they did it but it wasn’t effective.

“I know it’s the Christmas season and the pantomime season, but what do we see from the Labour front bench and the Right Honourable Gentleman?

“I’ve got some advice for the Right Honourable Gentleman. Look behind you. They’re not impressed and neither’s the country.”

Mr Corbyn is then alleged to have muttered the controversial phrase.

Both Tory and Labour MPs then took to the floor to call on the 69-year-old to apologise for what were deemed “misogynistic comments”, after he had left the chamber.

He was pictured watching the drama in the Commons unfold from a screen in Parliament’s tearoom.

Mr Corbyn then returned to the House to deny the allegations, claiming he said “stupid people”, referring to “those who I believe were seeking to turn a debate about the national crisis facing our country into a pantomime”.

Lip-readers from 121 Captions have since deduced that Jeremy Corbyn did murmur “stupid woman”, stating: “The mouth shows the shape of “Wo” and clearly ends with man. It does not look like “people” at all.

“Lips moving forward for “W” is very different from the plosive “P” shape in people.”

In an intervention that has amused many online, U.S. actor Rob Lowe also chimed in on the issue, supporting the claims that Corbyn said “stupid woman”.

In a Parliament so often divided over matters of Brexit, both sides of the House seemed to unite in condemnation of the Opposition Leaders’ alleged comments.

Labour MP Stella Creasy wrote on Twitter: “This is not ok.”

The Commons Speaker John Bercow claimed he did not see the remarks, so turned to video footage to weigh in on the exchange.

Bercow said that as the footage was inaudible, he could not make a ruling on the incident and would take “the word” of Mr Corbyn.
