Jonathon Dean

Introduction

Dr Jonathon Dean is a former UK doctor, General Medical Council registration number 7518208, whose name was erased from the medical register on 23 March 2026 after a Medical Practitioners Tribunal Service (MPTS) substantive hearing that sat from 16 to 23 March. At the time of the events concerned, he was an Anaesthetic Core Trainee 1. Before the tribunal, Dr Dean admitted that on 14 December 2018 he injected a woman, known in the determination as Ms A, with anaesthetic drugs in her bedroom for recreational purposes, penetrated her while she was sedated or anaesthetised, and that the conduct was sexually motivated. He was later convicted at Cambridge Crown Court of nine counts of theft and one count of possessing a Class A controlled drug, receiving 25 months’ imprisonment. The tribunal found his fitness to practise impaired and directed erasure.

Background Information

The published determination records limited biographical detail. It identifies Dr Dean as a doctor registered with the General Medical Council under number 7518208, working as an Anaesthetic Core Trainee 1 in December 2018, a junior post in anaesthetics. It does not set out his medical school, earlier training, or employing trusts.

It does document a pattern of conduct across several years: between 2022 and 2023, Dr Dean admitted attending Whipps Cross Hospital and the Royal London Hospital on multiple occasions against the instruction of senior colleagues and without appropriate reason. On 24 November 2023 he was convicted at Cambridge Crown Court of nine counts of theft and one count of possession of a Class A controlled drug, and on 5 April 2024 he was sentenced to 25 months’ imprisonment. His fitness to practise was finally determined in March 2026.

The Controversy or Incident That Led to Their Cancellation

Adjudicated vs. alleged. His Cambridge Crown Court convictions (nine counts of theft, one of possessing a Class A drug) are matters of court record. The 14 December 2018 conduct was ADMITTED by Dr Dean before the MPTS tribunal, which found it proved; regulatory findings are made on the tribunal’s own standard. Nothing here is an unproven allegation unless the determination says a charge was not proved.

A note on timing: the events below took place between 2018 and 2024, before this site’s coverage window. The cancellation event recorded here is the MPTS erasure of 23 March 2026, in which the tribunal weighed that earlier conduct and removed Dr Dean from the register.

Dr Dean admitted that on 14 December 2018, while an Anaesthetic Core Trainee 1, he acted without the necessary skills or competence to administer such medication outside a hospital setting and without appropriate monitoring equipment. He injected Ms A with anaesthetic drugs in her bedroom for recreational purposes, rendered her sedated or anaesthetised, penetrated her with body parts and an object, and left her without medical supervision. He admitted the conduct was sexually motivated.

The tribunal also considered disputed allegations and found further facts proved on the balance of probabilities: that Dr Dean refused to tell Ms A what he had done to her, offering only the vague answer of “Everything”, and that he knew his conduct left Ms A unable to consent to specific sexual acts, to withdraw consent, or to know what had taken place. By contrast, the allegation that he knew of Ms A’s mental-health vulnerability was found not proved.

The tribunal also dealt with his admissions that he attended Whipps Cross Hospital and the Royal London Hospital on multiple occasions between 2022 and 2023 against the instruction of senior colleagues and without appropriate reason, and with his convictions at Cambridge Crown Court on 24 November 2023 — nine counts of theft and one count of possession of a Class A controlled drug — for which he was sentenced on 5 April 2024 to 25 months’ imprisonment. His conduct amounted to serious misconduct and, taken together with the conviction, his fitness to practise was impaired.

Public Reaction and Consequences

The public record of this case is the regulator’s own. The MPTS published its determination following the March 2026 hearing, and independent record services such as MedicWatch have catalogued the outcome, listing Dr Dean among doctors struck off the register. No statements from professional bodies, employers, or the wider public form part of the determination, and this page claims no press coverage beyond it.

With fitness to practise found impaired by reason of serious misconduct and conviction, the tribunal directed that Dr Dean’s name be erased from the medical register. It further imposed an immediate order, so that the erasure took effect without waiting for the usual appeal period.

Current Status

As of 23 March 2026, Jonathon Dean has been struck off the UK medical register. Erasure means he is no longer permitted to practise as a doctor in the United Kingdom. Because the tribunal imposed an immediate order, the removal took effect straight away rather than after 28 days.

Erasure is otherwise indefinite: a doctor who has been struck off may apply for restoration only after a minimum of five years, any such application being considered afresh at that point. The determination records no conditions, undertakings, or interim arrangements, as none accompany an erasure.

Impact on Their Career/Life

The erasure ended Dr Dean’s medical career in the United Kingdom. An Anaesthetic Core Trainee 1 at the time of the 2018 incident, he was removed from the register in March 2026 and may not practise medicine in the UK unless a future restoration application, available after five years, succeeds.

The criminal proceedings ran alongside the regulatory ones: his conviction at Cambridge Crown Court on 24 November 2023 for nine counts of theft and one count of possession of a Class A controlled drug led to a sentence of 25 months’ imprisonment on 5 April 2024. The tribunal treated that conviction, together with the admitted sexual and clinical misconduct towards Ms A, as jointly rendering his fitness to practise impaired, and the resulting erasure stands as an indefinite removal from the public register.
