LBC presenter James O'Brien stated he feels "like a mug" for having previously defended Cambridge University professor Jason Arday, who resigned this week following an investigation into allegations of plagiarism and fabrication. O'Brien described his reaction to Arday's resignation as "very, very personal."

Arday, who had been Cambridge's youngest Black professor, resigned after the university launched an inquiry into claims that he had plagiarized parts of his doctoral thesis and exaggerated aspects of his personal life. In a statement, Arday said the "relentless accusations, speculation and public commentary" had taken a "profound toll."

O'Brien suggested that doubting Arday's credibility as a Cambridge professor solely based on his race would be indicative of racism, but acknowledged that Arday's subsequent actions made him feel foolish. "The fact that he thought I was someone that he might be able to persuade to stick up for him when he knew that he'd done wrong," O'Brien said, contributing to his feeling of being deceived.

Revelations about Arday's claims have surfaced since his resignation. According to a book proposal for his memoir, "Great and Unfortunate Things," Arday claimed to have experienced locked-in syndrome and testicular cancer. These specific anecdotes were present in the 2024 proposal but omitted from the final version of the book. The Atlantic reported inconsistencies in dates and characters between the two versions.

Prior to these, Arday faced allegations of plagiarizing sections of his PhD thesis from another student's research. Further scrutiny revealed other disputed claims, including assertions that he ran 600 miles in six days, raised millions for charity, and appeared in the television series "Seven Up," which began airing more than two decades before his birth in 1985. Institutions such as the University of Glasgow, Durham University, and Ohio State University also refuted his claims of holding academic positions at their establishments.

Following Cambridge's announcement on Wednesday evening that it would investigate Arday's conduct, he stepped down as a professor. He stated his decision was not a loss of faith in academia or Cambridge's values but a result of reaching the limit of what anyone should endure. "This decision should not be interpreted as a loss of faith in scholarship or in the values that first brought me to Cambridge. Nor should it be mistaken for an acceptance of the narratives that have surrounded me," Arday said in his statement.
