Conservative MP Sir Bill Cash says we should not use Article 50 to leave the European Union.
Article 50 is part of the Treaty on the European Union which sets out rules on how a member state should leave if they decide to.
David Cameron will resign by his party conference in October, and is giving the responsibility of triggering Article 50 to his successor.
The MP for Stone Cash however, disagrees that we should use Article 50, and thinks we should leave another way.
"It's about our democracy, it's not about being anti-European, it's about being anti-EU, because the EU is dysfunctional," he told Julia Hartley-Brewer. "It doesn't work, it creates massive unemployment and it just simply is a compression chamber waiting to explode.
"Article 50 binds us hand and foot, it's under the Lisbon treaty, which by the way we've just rejected in the vote. So that's number one, why would you use something that has already been rejected?
"The second thing is the fact it requires the consent of the European Parliament. It operates by qualified majority voting, and actually it puts you at a very significant disadvantage.
"Therefore I personally don't think we should use Article 50, and I’ve been saying this for some months.
"It should not be used at this moment in time, and probably never. Do it by way of legislation combined with parallel negotiations.
"This would then enable us to to appeal the European Communities Act, which is the channel for which all European legislation is imposed on the British people. Then you get back your self government."
He also commented on David Cameron's resignation.
"He had taken such a strong position which was out of sync with the British people.
"It was also out of sync with the ability from now on to be able to sort the thing out properly, because he was so committed to the views he expressed, for practical purposes I thought he would stand down."
