Speaker John Bercow has praised SNP MPs for their “solidarity” as dozens of the group pour into the Commons for each maiden speech.
With 50 new MPs, the greatly enlarged party grouping includes many rookie politicians making their debut in the chamber.
Every time one of them is due to speak, the SNP wing of the chamber quickly becomes packed.
And Mr Bercow praised the practice in the wake of Edinburgh East MP Tommy Sheppard’s first remarks to the Commons.
The Speaker said: “I know I’ll be joined by a great many colleagues in admiring the spirit of solidarity which motivates large numbers of members of one party to turn up at the same time.
“I say that in a spirit of genuine respect and so thank you for what you have said.”
He urged the 56-strong delegation to respect the long held convention that clapping is generally banned in the Commons chamber – despite the rule sometimes being ignored.
In his speech, Mr Sheppard offered an explanation for the incident. He said: “Mr Speaker, you gave us a gentle rebuke yesterday for the applause we gave in this chamber.
“We take that with good grace. We know, of course, it is not traditional practice in the chamber but we didn’t know just how unacceptable it might be found. We will refrain from doing that again.
“It will take us time to learn the processes that work here, it will take us time to get our feet under the table and it will take you time to get used to us. But I hope we will be able to do that in the weeks and months ahead.”
The SNP group has begun calling “hear hear” in concerted fashion, as is traditional in the Commons.
