Nicola Sturgeon has called on to resign following the Supreme Courts decision earlier today.
It comes after 11 judges unanimously concluded the prorogation of parliament for five weeks was deemed unlawful.
The First Minister said if the Tory prime minister did not offer his resignation then should "come together to force this Prime Minister from office".
In an interview from in , she said: "I think Boris Johnson should resign.
"A prime minister with any honour would tender his resignation today.
"If the Prime Minister isn't prepared to do the decent and honourable thing and resign, then parliament should quickly come together to force this Prime Minister from office."
Her comments came after Labour leader Jeremy Corbyn called for Johnson to "consider his position".
Addressing the Labour Party conference in Brighton, Mr Corbyn said: "It shows that the Prime Minister has acted wrongly in shutting down Parliament.
"It demonstrates contempt for democracy and an abuse of power by him. The Supreme Court, therefore, passes the baton to the speaker to recall Parliament.
"I will be in touch immediately to demand that Parliament is recalled so that we can question that prime minister, demand that he obeys the law that has been passed by Parliament and recognise that our Parliament is elected by our people to hold our Government to account.
"A Labour Government want to be held to account. We wouldn't bypass democracy.
"And I invite Boris Johnson in the historic words to consider his position."
Mr Corbyn said Boris Johnson would become "the shortest-serving prime minister there has ever been" if he resigned.
He added: "So, obey the law, take no-deal off the table and have an election to elect a government that respects democracy, that respects the rule of law and brings power back to the people, not usurps it in the way that Boris Johnson has done."
House of Commons speaker John Bercow announced parliament will resume at 11.30am tomorrow.
