On Good Morning Britain he suggested that a general election would be "the real People's Vote" because it would give the public the chance to change the team carrying out the negotiations, replacing Theresa May with a Labour government.
The Labour conference in Liverpool is to vote tomorrow on a motion to keep "all options on the table", including a second referendum.
But the exact wording of the motion to be put to a vote at the party's conference on Tuesday states only that "if we can not get a general election, Labour must support all options remaining on the table, including campaigning for a public vote".
We'll be arguing that it should be a vote on the deal itself, and then enable us to go back and do the negotiations.
As the party gathers in Liverpool for its annual conference, the issue remains a talking point.
"But we will push, if Theresa May fails, we will push for a general election because that's the choice that people should have".
The Sunday Telegraph says Corbyn's comments "pave the way for a significant change in Labour's Brexit policy", and come just two days after Theresa May urged the Labour leader to clarify his position on Brexit, "amid concern that a Labour U-turn could jeopardise any deal reached with Brussels and prevent the United Kingdom from leaving the EU". "This year will just be a staging post towards the fully democratic party that we want", he said.
He added: 'That is what happens when you return the party to the members'.
The Labour Party says the motion is not "prescriptive" on what the question of any second referendum should be, leaving options open to gauge the lie of the land if, or when, such a vote needs to take place.
The rally was punctuated by cries of "stop Brexit" from the audience, but most speakers steered clear of the topic, ahead of a conference which Labour wants to focus on housing and workplace rights.
"It was then agreed that if we can not get a general election Labor must support all options remaining on the table, including campaigning for a public vote", the unnamed source said.
Mr Corbyn and shadow chancellor John McDonnell wrote to all Labour council leaders in 2015 calling on them to resist calls to set illegal budgets.
The key paragraph in the document states: "If we can not get a general election Labour must support all options remaining on the table, including campaigning for a public vote".
Labour leader Jeremy Corbyn and other party chiefs oppose that idea, saying Labour must honor voters' 2016 decision to leave.
John McDonnell said the vote should "respect" the 2016 result and only be on the government's negotiated deal with Brussels.
'And if the Prime Minister thinks we'll wave through a vague deal asking us to jump blindfolded into the unknown she can think again.
McCluskey told Labour MPs who have claimed pro-Corbyn activists are trying to get rid of them they should accept party members had the right to choose who their representatives were.
Corbyn has so far tried to avoid the divisive subject, instead sticking to promoting a domestic social agenda that helped him upset the odds at last year's general election and strip May of her parliamentary majority.
And with the governing Conservatives in disarray, there are growing calls for Corbyn to take the lead - something he said he was ready to do if May did not get her deal through parliament.
"The opportunity before the United Kingdom as a result of Brexit is huge: but if we squander it, the "new normal" of limited economic growth will prevail, with an European Union system that is failing to respond to the challenges of the modern economy", it said. We will vote down a blind Brexit'.
