Geoffrey Cox appeared to let slip Government plans to table an election motion as he responded to a call for Boris Johnson to resign.
The Attorney General was being scrutinised over prorogation in the Commons in the wake of yesterday's damning Supreme Court ruling which deemed it unlawful.
In a heated first session back for Parliament, Patricia Gibson, of the SNP, asked Mr Cox: "Is it not the case that the decent thing for the Prime Minister to do is go?"
Mr Cox responded: "Can I encourage her then to ensure that we vote for the election motion that will come before the House shortly?
"That way she can ensure what she hopes, she thinks, no doubt, will take place."
He then added: "But the reality is, I don't agree, the Supreme Court found no impropriety on behalf of the Government, the Prime Minister, or anybody else."
It comes after Mr Cox defended the Government on the prorogation, stating its actions had been done in good faith.
Despite this, he said it accepted the agreement of the justices and that it had "lost".
This was followed by chaotic scenes in the Commons, which the Speaker John Bercow said became a "rant fest", in which Mr Cox blasted what he called a "dead Parliament".
Mr Cox stunned MPs with an attack on the current Parliament, saying it was “dead” and that MPs were too “cowardly” to call a general election.
Blasting Parliament for not agreeing on a way to leave the EU having rejected the previous withdrawal agreement as well as moving to block no deal, he said: "This Parliament is a dead Parliament."
To cries and jeers he said: "It has no moral right to sit on these green benches."
When the Speaker interrupted he said: "They don't like to hear it Mr Speaker. They don't like the truth.
"This Parliament is a disgrace. Let me tell them the truth, they could vote no confidence at any time. But they're too cowardly.
"This Parliament should have the courage to face the electorate, but it won't.
"Because so many are about preventing us leaving the European Union at all.
"But the time is coming Prime Minister, when even these turkeys, won't be able to prevent Christmas."
Mr Cox’s performance dampened hopes that Mr Johnson would make a show of contrition over his attempt to shut down Westminster for five weeks.
He was being quizzed on Parliament's suspension on the first day back for Parliament, which was recalled by Mr Bercow yesterday.
Throughout the session, Mr Cox said he felt there should be an election, which the PM has also called for.
However, the opposition has ruled out backing one until it is confident the chances of a no deal Brexit are entirely ruled out.
