Sir Vince Cable, who looks set to be the next leader of the Liberal Democrats, has speculated that Brexit "will never happen" as people realise the negative economic implications for the UK.
Speaking on the BBC's Andrew Marr show, Cable (published) cited "enormous" division in the Labour and Conservative parties on the contentious issue, as well as Britain's "deteriorating" economy as a reason for rethinking Brexit.
He said: "People will realise that we did not vote to be poorer, and I think the whole question of continued membership will once again arise."
Cable, who looks set to be the next Lib Dem leader after the resignation of Tim Farron, has also told the BBC he wants to work with his rivals to block Prime Minister Theresa May's 'hard' Brexit plans.
He is intending to form a cross-party coalition to oppose a UK exit from the single market, which is currently the official policy of both the Labour and Tory parties.
He told the BBC: "I am beginning to think Brexit will never happen. The problems are so enormous, the divisions within the two major parties are so enormous. I can see a scenario in which this does not happen."
However, Eurosceptic Conservative MP Owen Paterson dismissed his comments, saying Cable was just "chucking buckets of water around" and forgetting the "huge" vote in favour of the Leave campaign.
Meanwhile, Cable said that any Labour MPs who disagree with their leader Jeremy Corbyn's position on Brexit are welcome in his party and predicted further divisions within Labour.
Cable is not expected to have a challenger for his leadership of the Lib Dem party, but intends to produce a manifesto nonetheless.
