Paula Sherriff, who represents the Dewsbury constituency, said the Prime Minister - who was also criticised for connecting murdered MP Jo Cox to Brexit - had “continually used pejorative language to describe an Act of Parliament passed by this House” when using the term “Surrender Bill”.
She added: “We should not resort to using offensive, dangerous or inflammatory language for legislation that we do not like and we stand here under the shield of our departed friend with many of us in this place subject to death threats and abuse every single day.
“And let me tell the Prime Minister that they often quote his, words Surrender Act, betrayal, traitor, and I for one am sick of it.
“We must moderate our language and it has to come from the Prime Minister first.”
She added: “He should be absolutely ashamed of himself.” Her words prompted applause from the opposition benches.

However, responding to the criticism, Mr Johnson sparked fury when he said: “I have to say, Mr Speaker, I’ve never heard such humbug in all my life.”
Shouts of “shame” could be heard across the chamber, while Labour’s Tracy Brabin, who was elected to the seat after Mrs Cox was killed during the 2016 EU referendum campaign, also called for the PM to moderate his language.
She said: “As the woman who has taken over a seat left by our dear friend Jo Cox, can I ask him in all honesty as a human being please, please will he going forward moderate his language so that we will all feel secure when we’re going about our jobs.”
Mr Johnson replied: “Of course there will be an attempt to try to obfuscate the effect of this Act, but it does – the Capitulation Act, or the Surrender Act or whatever you want to call it – it does, I’m sorry, but it greatly enfeebles, it greatly enfeebles this Government’s ability to negotiate.
“But what I will say is that the best way to honour the memory of Jo Cox and indeed the best to bring this country together would be, I think, to get Brexit done.”
