"The Biggest Scandal Since Lobotomies" - Tavistock Whistleblower Marcus Evans

27 November 2025

With Marcus Evans

90 minutes

Psychoanalyst Marcus Evans spent 45 years inside British psychiatry — including time as a governor at the Tavistock and Portman NHS Trust — before resigning in 2019 over concerns he could no longer set aside. In conversation with Stella O'Malley and Mia Hughes, he draws on that clinical depth and his new book to argue that gender medicine represents not just bad practice but a fundamental abandonment of what ethical psychiatry is supposed to do.

Marcus Evans does not arrive at this conversation as an outside critic. He arrives with 45 years in British psychiatry — including a long role at the Tavistock and Portman NHS Trust, where he served as both clinician and governor before resigning in 2019. Stella O'Malley and Mia Hughes spend the early part of the episode drawing out what led him there: the months of trying to get the institution's executives to engage seriously with the Dave Bell report, the resistance, and the point at which remaining on the board became ethically impossible. It is a backstory that reframes everything he says. The historical record he lays out is more damning than many listeners will expect. His wife Sue Evans was raising concerns at Tavistock as far back as 2005, and a subsequent internal report in 2006 anticipated much of what the Cass Review would eventually conclude after a formal multi-year investigation. Marcus's new book, Identity and the Foundational Myth, is in part an attempt to give that buried history a proper psychoanalytic accounting, and the episode gives him the space to explain what the clinical establishment was choosing not to see across those two decades. The clinical argument at the heart of the conversation is the comparison between affirming gender dysphoria and affirming anorexia. Marcus frames it precisely: when a patient believes food is poisonous, the therapist's job is to understand the belief, not endorse it. The same logic applies to a patient whose identity has become entirely organised around the conviction that they were born in the wrong body. To affirm that conviction without question is not compassionate — it is a form of collusion that closes off the therapeutic inquiry that might actually help. Several therapists, he notes, have acknowledged in private that this is exactly what happened to them. Marcus introduces the concept of the overvalued belief to explain how both patients and institutions became captured by an idea that functions more like dogma than diagnosis. Questioning it is experienced as attack; genuine clinical curiosity becomes professionally dangerous. His assessment of the new puberty-blocker trial is correspondingly sharp: a two-year follow-up window is nowhere near sufficient for a medical intervention whose consequences — on fertility, on surgical outcomes, on the entire developmental arc of a young person's life — only become visible much later. What Stella and Mia draw out across this exchange is the sheer weight of experience behind each of these arguments. Marcus Evans is not reacting to a political controversy; he is drawing on decades of serious clinical work with patients in real distress and asking what it actually means to help them. The publication of Identity and the Foundational Myth makes this a timely conversation, and the episode covers ground — from the buried 2006 report through to his position on adult transition — that is essential context for understanding how a scandal of this scale was allowed to unfold inside one of Britain's most respected psychiatric institutions.
