The arch Remoaner claimed Brexiteers were still living in a “fantasy world” if they believed leaving the EU will be as easy as signing a “free trade agreement”.
Veteran host Mr Humphrys speared the anti-Brexit figurehead, as listeners took to Twitter to vent their frustration at Mrs Miller for her desperate attempts to reverse the result of last June’s referendum.
Speaking on Radio 4’s Today programme, John Ashworth, who quit his role in the British Chambers of Commerce to campaign for Leave, claimed that it was wrong for the success of Brexit to be judged on whether the Government can secure a “free trade agreement”.
He added: “It’s a big mistake, the reality is it doesn’t really matter if we get one or not because our trade tariffs will be less than our net contributions.”
Gina Miller received a slap down from John Humphrys for suggesting Brexiteers live in 'fantasy land'
Evidence suggests the further we are from referendum, the people are now accepting it
Mrs Miller instantly hit back, claiming Brexiteers are “still in a fantasy land” over their plans to guide the UK out of the EU.
She said: “It’s still a fantasy land. It’s so much more complex than a free trade agreement – it’s about our airways, environment and loss of skills in our public services.
“In the City there’s a huge number of people coming from the EU and there are already agencies complaining that there’s a loss of people applying for jobs. – this is so complicated.”
However, the businesswoman was swiftly interjected by Mr Humphrys who insisted voters – Remain or Leave supporters – simply want Brexit to be completed.
“You may or may not be right, but the evidence suggests the further we are away from the referendum, the people who voted to stay in are now accepting it’s not that bad to pull out,” he blasted.

Mrs Miller proceeded to claim her Brexit bothering campaign, Best for Britain, had conducted research which proved even Leave voters didn’t want a "hard" Brexit and to leave the single market.
She said around “50 per cent” of voters didn’t want the form of Brexit being pursued by Theresa May, who is expected to be elected at tomorrow's General Election.
This prompted a furious social media response, with users taking aim at her campaign’s “research”.
One user wrote: “Gina Miller: ‘This is not polling, it’s direct research.’
“What the hell does that mean? Asking your mates?”
