Matt Goodwin and Andy Twelves caught in fiery clash over author's new book Suicide of a Nation

In the days after its release, Mr Twelves condemned the book for its "false quotes and basic misinterpretations of data that appear to be AI hallucinations".

He pinpointed "quotes" from Roman statesman Cicero, as well as economist Friedrich Hayet and theorist James Burnham which, the commentator insisted, do not exist.

However, the academic adamantly denied the claims.

Defending his work on GB News, Mr Goodwin vowed he "stood by his book which is the only book that's telling people the truth about how and why we are losing our country".

He added: "I wrote this book over the period of four months away from my friends and family, because I think the British people deserve to know the truth.

"I deliberately did not publish the book with a mainstream publisher because publishing, in case people out there haven't noticed, has been completely captured by woke activists and sensitivity readers who would never, ever have allowed me to publish a book like Suicide of a Nation."

Meanwhile, Mr Twelves fired back: "If publishing is completely captured by the woke left, it would seem that fact checkers and copy editors are also there are not just factual errors in this book, but just basic spelling and grammar ones.

"And it's not even misattributed quotes of Cicero, of Livy, of Hayek, of Scruton, of whoever.

"There are just basic untruths that Matt knows. It said in 2019 that Boris Johnson was in Opposition.

"You were a pundit in 2019, Matt. You knew Boris Johnson was not in Opposition. You go to quote him in that same phrase.

"And the quote from it is from the 2019 General Election manifesto of the Conservatives. Tell me, who was the leader of the Conservatives and the sitting Prime Minister at that time?" he derisively added.

But the commentator refused to stop there. He went on to condemn Mr Goodwin's work for "false statements fundamental to the book".

Mr Twelves added: "You don't recognise exponential growth, and it's not even occasional sloppiness," he blasted.

"Claims about immigration levels, welfare use, language decline, even baby names are just false.

"If you're going to open your book up with a quote about Arnold Toynbee and the suicide of nations, you might want to make sure your own argument isn't built on intellectual self-harm.

"This isn't political. It's just about truth," he finished, delivering his opening remark.

But Mr Goodwin said he would dispute Mr Twelves's claims, declaring: "Artificial intelligence is a research tool that every journalist, every academic, every data analyst now uses.

"Now, Andy, I believe I'm right in saying you've never written a book or you've not managed a large scale data project that's gone through peer review. Everybody today uses AI as a research tool.

"If you are cross-checking your figures and statistics with official data sets, then it's a completely acceptable thing to do."

But, since Mr Twelves had accused Mr Goodwin of using AI to write "large parts" of the manuscript, the author uploaded his work to five AI detection sites.

ZeroGPT, Mr Goodwin claimed, identified 2.2 per cent of the book was based on artificial intelligence, while the average for most written works was 10 per cent.

The comments, the academic said, said: "This does not read like an AI written book. There is no credible evidence this book was written by AI. There's emotionally driven language, there's escalating rhetoric. There's signature voice writing.

"There's a long range argument structure. There's intentional narrative control."
