The former deputy prime minister claimed the “British people should have their say” on how Britain leaves the EU and there was “no clear manifesto” on the move.
Speaking on Sophy Ridge on Sunday, the former Lib Dem leader said there was a “huge question” on what type of Brexit the UK pursues over the next couple of years.
He joined Lib Dems leader Tim Farron on a Unite for Europe march yesterday, at which Mr Farron was asked "what is the point?" for going on the protest which was trying to derail Brexit despite Britain's exiting of the EU already being put into law.
Ridge did not hold back today as she asked Mr Clegg: “The Lib Dems have been supporting a second referendum on the deal, you and your leader were at this march, the anti-Brexit march yesterday. The Lib Dems have amended the Brexit bill. Are you in denial that it’s going to happen?”
But the MP for Sheffield Hallam was resolute and said Brexit would “affect almost every aspect of our lives”.
Nick Clegg dismissed suggestion he was "in denial"
I never got, you never got, no one looking at this programme got a clear manifesto from Nigel Farage, Boris Johnson, Michael Gove
He replied: “No, I think if the Brexiteers last summer had spelt out to the British people exactly what kind of Brexit they were pursuing, if there’d been agreement between your previous guest Nigel Farage, Boris Johnson, Michael Gove and the rest of them… I never got, you never got, no one looking at this programme got a clear manifesto from Nigel Farage, Boris Johnson, Michael Gove on a cross-party basis saying we want you to leave the European Union and this is how we will do it.
“So, in other words, there’s a huge question now over the next two years about what kind of Brexit, hard or soft, inside or outside the single market, are we going to abide by the European Court of Justice, what kind of changes to freedom of movement, what kind of changes to our universities, what kind of changes to our farmers, our fishing and so on and so forth.
“All of that is going to affect almost every aspect of our lives. Once we know what it means in practice, rather than the utopian promises that all will be brilliant and all will be well, of course we think it is right, not a second referendum, that the British people should then have their say.

“Because there’s going to be a deal, right? Well at least we hope there is. There’s going to be a deal, who then has to decide upon that deal? Is it the politicians, is it Theresa May on her own, or is it the people and we think, quite rightly, in keeping with the decision last summer, it should be the people.”
Lib Dem leader Tim Farron told thousands of anti-Brexit demonstrators on Saturday that Theresa May “does not represent the 52 per cent” and called for Leavers and Remainers to unite for a final say on the Brexit deal.
Thousands of demonstrators joined Saturday's Unite for Europe march, starting outside the Hilton Hotel in Park Lane, London.
From there the protestors marched through Trafalgar Square and down past Downing Street, ending with a rally in Parliament Square – where hundreds of floral tributes to the victims of Wednesday's terror attack have been laid.
The march coincided with the EU's 60th anniversary celebrations in Rome, where leaders of the other 27 member states gathered to discuss plans for the future of the union without the UK.
The Prime Minister will trigger Article 50 and begin Britain's historic departure from the European Union on March 29.
The move will kick-start the beginning of the two-year countdown until Brexit is complete.
