"Humbug" was part of the response to this,
"I genuinely do not seek to stifle robust debate, but this evening the Prime Minister has continually used pejorative language to describe an Act of Parliament that was passed by this House. I am sure you would agree, Mr Speaker, that we should not resort to the use of offensive, dangerous or inflammatory language about legislation that we do not like.​
We stand here, Mr Speaker, under the shield of our departed friend. Many of us in this place are subject to death threats and abuse every single day. 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 that has to come from the Prime Minister first, so I should be interested in hearing his opinion. He should be absolutely ashamed of himself."
Was the PM's reply appropriate?
