Dominic Raab has insisted that the risks associated with a no-deal Brexit have been "magnified beyond all proportion".
The former Brexit secretary, who is backing Boris Johnson in the leadership race, defended the potential Prime Minister's pledge to deliver Brexit on October 31 "do or die".
"This is a historic cross roads for the country, there's no doubt there's some risks there," Mr Raab told talkRADIO's Julia Hartley-Brewer.
"Some of the risks that have been talked about are correct, I just think they've been magnified beyond all proportion."
There has been fierce opposition to Mr Johnson's concrete pledge to leave the EU at the end of October, particularly his suggestion that he would be willing to suspend Parliament in order to push a no-deal Brexit through.
"We have seen all the risk and the downsides eclipse the considerable upside," Mr Raab continued. "The ability to control our own laws, our borders, our money, our ability to do free trade deals."
"We have got a US president who is no longer saying we're at the back of the queue for a free trade deal, but is really rather positive about this country."
Despite his support for Mr Johnson in the leadership contest, Mr Raab refused to say whether he would be supporting any Brexit deal he brought to the Commons.
"I will wait and see the precise terms," he said. "The crucial thing is Boris has said that he will take what he describes as the 'serviceable bits' of the [Theresa May's] deal, things like citizens' rights."
He continued: "Plus crucially the ambition to get a best in class free trade agreement with the EU, which is the best way to solve the Northern Ireland issue because it relates to our wider approach to checks at the border, not just with Northern Ireland, but more generally."
