Scotland 's 56 new SNP MPs rebuffed Westminster customs, wearing white roses, clapping in the chamber and even, allegedly, contributing to the absence of the traditional Queen's Speech quip.
Labour MP Dennis Skinner is known for his bon mots at the start of the event.
But this year he said he was too busy "fighting some other battles...I was fighting the Scot Nats."
Mr Skinner, also said that he has been getting up at 6am to secure his place in the Commons, in what has become known as 'Seatgate and the Battle of Buttockburn - a row between the SNP and Labour for positions on the benches.
Later the Speaker told off SNP MPs after they clapped a number of times.
Traditionally, MPs are allowed to speak in the Commons only after they have made their maiden speeches, meaning most of the SNP group cannot currently make their voices heard.
Mr Bercow said: "Can I say at the start of the Parliament that the convention that we don't clap in this chamber is very, very, very long-established and widely respected?
"And it would be appreciated if members would show some respect for that convention."
The SNP group also attended the state opening of parliament wearing white roses in reference to the poem by Hugh MacDiarmid, 'The Little White Rose of Scotland'.
'The rose of all the world is not for me
I want for my part
Only the little white rose of Scotland
That smells sharp and sweet - and breaks the heart.'
While unusual at Westminster the move was less of a break with convention for the SNP.
The first intake of SNP MSPs also wore a white rose when the Scottish Parliament was opened in 1999.
