Bernard Jenkin berated the European bloc for being “incapable” of making “sensible decisions” but remained confident the UK would secure agreements in other areas.
The Harwich and North Essex MP responded on BBC News after the former Deputy Prime Minister said a “no deal outcome” was a “huge risk not worth taking”.
He said: “Well I think Nick Clegg is just doing his very best to reduce expectations and I think he’s right on a lot of points and I think we have to be realistic.
“The idea of having a fully comprehensive trade deal with the EU at the end of two years I think is a big stretch. And not because we can’t negotiate that.
Barnard Jenkin blasted Nick Clegg for painting a "disaster scenario"
The disaster scenario painted by people like Nick Clegg are just ridiculous
“It’s because the EU seems to be determined to re-erect trade barriers when the rest of the world is trying to bring them down and that’s one of the reasons why we’re leaving the EU.”
Mr Jenkin questioned the European Union’s intentions before insisting there would be agreements made in other areas.
He said: “They’re either pursuing the wrong policy or they’re just incapable of making sensible decisions that are in everybody’s economic interests, but of course, there will be agreement on things like customs facilitation.”
The Brexiteer said the UK would continue to work together on security and said there would be a deal made on the rights of EU citizens in the UK.

He added: “The disaster scenario painted by people like Nick Clegg are just ridiculous.”
It comes after Mr Clegg said it would not be possible to have a trade deal ratified by 27 other parliaments by 2019.
He said: “I think a no deal outcome is the very worst outcome for the United Kingdom. It would create unprecedented economic and legal uncertainty and really would jeopardise the British economy in quite a big way.
“So I think that it’s a huge risk not worth taking but there’s clearly a lot of people who are agitating for that to happen.”
