TV personality Kim Woodburn shouted “scum” on numerous occasions during a fiery debate about the Angela Rayner row.
A story in the Mail on Sunday revealed how an anonymous Tory MP accused the Labour deputy leader of attempting to distract Mr Johnson by crossing and uncrossing her legs in the Commons chamber.
But Ms Woodburn suggested Brits need to remember how Ms Rayner behaved when she called Tory MPs "scum".
She told Dan Wootton Tonight: “Most of them are men, and she calls them all utter scum which is the filth of the earth, and she expects you to be sweet about her. You get what you give.

Labour deputy leader Angela Rayner

“She’s no wilting flower and a position she’s got to be talking like that, she shouldn’t have the position.
“And this started off as tittle tattle with the Conservatives ‘oh she’s showing her legs’ they know she wasn’t, it’s men’s talks.
“Was Boris there with exploding y-fronts? Are we all exaggerating this?”
Speaking after the article was released, Ms Rayner lashed out at the “lies” being briefed about her.
The Ashton-under-Lyne MP said on Twitter: “Boris Johnson’s cheerleaders have resorted to spreading desperate, perverted smears in their doomed attempts to save his skin.
“They know exactly what they are doing. The lies they are telling.”
She said Mr Johnson and his backers “clearly have a big problem with women in public life” and that they “should be ashamed of themselves”.
“I won’t be letting their vile lies deter me. Their attempts to harass and intimidate me will fail,” Ms Rayner added.
