The man was weighing in on the fiery televised debate, which has just resumed a new series following Parliament’s return from its annual summer break.
The panel was discussing a question posed by audience member George Stowe, who asked whether the Tory party needed to oust Theresa May to save Brexit, when the audience member added his thoughts.
In a seething rant, the man wearing a black cap said: “What happened to Brexit means Brexit?
“We waited two years just to vote on Brexit. Now it has been another two years.
“We have known all along that everybody in Parliament, every MP, doesn’t want to leave Europe. We have known that from the start.
“Just get out. Get out now as quickly as possible.”
Another audience member offered his views that former Brexit Secretary David Davis, who resigned from the cabinet following the unveiling of Theresa May’s Chequers proposals, was the standard-bearer for the Leave process.
He said: “David Davis was the champion for Brexit.
“He has done a lot of the negotiations, he is one of the most credible men in British politics and he has walked away.
“You must ask the question, why?”
The audience member suggested the EU’s chief negotiator Michel Barnier had recently appeared to have changed his tact towards the UK and was suddenly acting in a friendlier fashion.
He said: “You must also ask yourself the question, why?
“The answer is: the Chequers deal is not credible.
“It is credible for Europe. It is not credible for the people of Great Britain.”
Prospective Parliamentary candidate for the Labour Party, Faiza Shaheen, also took part in the animated TV debate in Banbury, Oxfordshire.
Ms Shaheen, who is director of a think tank called the Centre for Labour and Social Studies, claimed the Government was incompetent.
The left-wing policy wonk said: “We need policies that address the issues.”
She added: “For me, I struggle with a People’s Vote because I think it could get very nasty, Brexit has already been incredibly divisive.
“If we want to address the issues relating to Brexit, we need broader policy changes.”
Ms Shaheen, who called for a “Brexit package” on policy, claimed prominent Brexiteer figures such as Jacob Rees-Mogg needed to be held accountable.
She said: “If it is true that we can’t get the Brexit deal they said we could, then I think there is a question about whether we need to go back and say, ‘what does Brexit look like?’
“We can’t keep going round in circles, it is just not possible.”
She added: “The best way I have heard it described is: we are like scrambled eggs and you can’t ‘unscramble’ scrambled eggs.”
