Jeremy Corbyn has said he will not call a vote of no confidence until a no-deal Brexit is off the table.
The Labour leader said once it is clear no-deal has been stopped, his party would also push for a general election.
Earlier this month, Parliament passed the Benn Bill that gave Prime Minister Boris Johnson until October 19 to secure a deal with the EU or call for a three-month extension.
"Until it is very clear that the application will be made, per the legislation, to the EU to extend our membership to at least January, then we will continue pushing for that and that is our priority," Mr Corbyn told BBC’s Radio 4 Today Programme.
"When that has been achieved we will then be ready with a motion of no confidence."
He continued: “I’m very happy to have a general election once we have taken a no deal off the table and the EU has granted that extension.”
Mr Corbyn brought forward his Labour Party Conference speech so he could return to Westminster on Wednesday.
He has called for the PM to resign as Parliament today reopens after the bombshell Supreme Court ruling that his five-week shutdown was unlawful.
He told the BBC that he thought the Prime Minister would have received advice from Government lawyers that proroguing Parliament for five weeks was “questionable”.
“I would have thought it would have been pretty obvious that the course the PM was set on was very risky and an affront to our democracy,” he said.
Mr Corbyn also called for the PM to apologise: "I think he should apologise to her (the Queen) for the advice he gave her but, more importantly, apologise to the British people for what he's done in trying to shut down our democracy at a very crucial time when people are very, very worried about what will happen on October 31."
