The discussion began with the foursome talking about the vote MPs will take later today on whether to build a third runway at Heathrow.
Conversation then turned toward Boris Johnson, where Andrew criticised his leadership.
He said: “The typical thing of Boris is that he’s not going to turn up and vote, a junior minister has been forced to resign because they’re not prepared to vote for it.
“Him as Foreign Secretary not to even be present sort of sums him up.”
Susanna chimed in: “After Brexit, where are we going to be with Airbus?”
Andrew then began to say: “Whether Brexit happens or not…”
“You think Brexit is not going to happen?” Susanna questioned.
Nigel then chuckled before Andrew jumped in to discuss protests against Brexit from those who wanted to remain in the European Union.
But Piers then brought up the demonstrations which were held against the decision to go into the Irag war made under Tony Blair.
The host questioned: “The will of the people was not recognised then, why should they do it when it’s 100 thousand [people]?”
Andrew defended: “A big difference between then and now is we had a PM who believed he was doing the right thing.
“If you press Theresa May she doesn’t really believe in it.
Piers then exclaimed: “She’s a remainer.
“You’re the one being disingenuous!
“We’ve already had the damn will of the people. The only point of a referendum is to give people the vote!”
The debate raged on about whether Brexit would actually be going through, where Nigel made his feelings clear and confirmed it would be happening.
He explained: “I think we could be a lot better off.
“The vote was about the independence of the people.”
Andrew then chipped in: “I think peoples opinions will start to change.”
Nigel defiantly added “We’re leaving.”
