An Indian-origin surgeon who spent more than four decades in medical practice, including 25 years with the UK’s National Health Service (NHS), has been struck off the UK medical register for posting antisemitic abuse on social media.
Manoj Sen, who qualified as a doctor in 1983 from the Medical College and Hospital, Kolkata, and moved to the United Kingdom in 1985, was removed from the register following a Medical Practitioners Tribunal hearing held from September 22 to 25. The tribunal found that his conduct amounted to serious misconduct after he made a series of antisemitic remarks against another user on Facebook in October 2023. As per reports, Sen did not attend the hearing.
The incident occurred on October 10, 2023, when Sen engaged in an online exchange with a man referred to as Mr. A, three days after the Nova festival massacre.
During the exchange, he used offensive language and slurs, referring to Mr. A as “Jewboy”, “circumcised vermin”, and a “Jewish rodent”.
He also wrote, “When dealing with circumcised vermin like you, not even the strongest measures will help,” and added that he was “regretful enough rats were not liquidated at Auschwitz”.
In further comments, he wrote “Die Juden sind unsere Ungluck (The Jews are our misfortune)”.
Mr. A reported the matter to the police and the General Medical Council (GMC), describing the posts as “sustained antisemitic abuse by a doctor”. Police later described the comments as “repeated antisemitic slurs and abuse online” and confirmed that Sen had accepted a police caution on November 10, 2023, for “racially/religiously aggravated harassment/alarm/distress by words/writing”.
In a written statement, Sen said: “I must have lost my senses as in the heat of the moment I made wrongful and injudicious remarks – for which I have apologised in public on Facebook as well as privately to the police.”
The tribunal concluded that the comments were antisemitic and seriously offensive, particularly the references to Auschwitz and crematoriums, which it said “went far beyond any acceptable or lawful expression of opinion”.
It stated that “the language used suggested a deep hostility towards Jews as a group, rather than merely a personal attack on the complainant”. The panel also noted that there was no written apology and that “the degree of hostility expressed in his comments is fundamentally incompatible with the duty of a doctor to treat patients equally”.
On August 13, 2025, Sen informed the GMC that he did not wish to participate in the hearing, writing, “to go ahead and good luck”. The tribunal ordered his immediate erasure from the medical register, concluding that his actions had brought the medical profession into disrepute.
London North West University Healthcare NHS Trust, which operates Northwick Park Hospital where Sen worked earlier, said, “Mr Sen no longer worked for the trust when he made these comments, but we do not tolerate hate speech or discrimination of any kind and take immediate action when such behaviour is brought to our attention.”
