★★★★★ A sharply observed, meticulously researched and often darkly funny portrait of Peter Mandelson, delivered through a performance of such precision that it becomes less an impersonation and more an act of political possession. Richard Stirling doesn’t just play Mandelson — he inhabits him.
Mandy: Prince of Darkness is a one‑man political biography told from inside the mind of one of the most enigmatic figures in modern British politics. Stirling structures the piece around Mandelson’s own recollections, justifications and rhetorical flourishes, anchoring each chapter of his career with projected headlines and dates behind him. It’s a simple device, but an extremely effective one: the audience is never left drifting. Every scandal, every comeback, every resignation is pinned to a moment in time.
The effect is cumulative. You begin to realise just how many times Mandelson fell, rose, fell again, and rose again — until finally, as the show concludes, he meets the one scandal he cannot return from.
Performance: A Masterclass in Political Mannerism
Richard Stirling’s performance is the engine of the show, and it is extraordinary. He captures Mandelson’s mannerisms with forensic accuracy: the sly, fox‑like half‑smile; the careful modulation of tone; the way he leans into a phrase as if it were a tool he’s about to use.
But the real brilliance lies in the switches. When Mandelson quotes Tony Blair, Stirling shifts instantly — a recognisable Blair arm‑and‑hand gesture, the slight lift in vocal timbre, the earnestness that borders on sermonising. It’s subtle, funny, and deeply effective. He doesn’t break character; he folds Blair into Mandelson, showing how the two men lived inside each other’s political space.
This is mimicry at its highest level: not caricature, but observation.
Language, Manipulation & the Limits of Persuasion
One of the show’s most interesting threads — and one that came through strongly in your reflections — is the tension between Mandelson’s linguistic brilliance and the public’s instinctive scepticism.
Stirling presents Mandelson as a master manipulator of language: elegant phrasing, polished argument, the kind of rhetorical charm that can make nonsense sound like strategy. But even at his most persuasive, there’s a sense that ordinary people can smell when something isn’t quite right. The show captures that beautifully. You hear the justification, you admire the craft, but you don’t buy the conclusion.
It’s a portrait of a man whose intelligence was both his greatest asset and his greatest blind spot.
The Epstein Irony
The final act of the show deals with the Epstein scandal — the moment that ends Mandelson’s long cycle of comebacks. Stirling plays it with a deliberate irony: the arch‑strategist suddenly presenting himself as naïve, manipulated, unaware.
The email exchanges shown on screen undermine that claim. They hint at a man who knew exactly what he was doing, or at least knew enough not to pretend innocence convincingly. It’s a quietly devastating moment, and Stirling lets the audience draw its own conclusions.
Private Life, Public Persona
Stirling also touches on Mandelson’s approach to his private life. He didn’t hide being gay, but he didn’t foreground it either. It was simply part of who he was, not a political tool nor a public performance. The show treats this with sensitivity, acknowledging the complexity without sensationalising it.
Verdict
Mandy: Prince of Darkness is a superb piece of political theatre: sharp, intelligent, and anchored by a performance of remarkable skill. Richard Stirling gives us a Mandelson who is manipulative, charming, brilliant, flawed, hardworking, private, and ultimately undone by the one scandal he could not outmanoeuvre.
It’s a portrait of a complicated man, delivered by an actor who understands that complexity down to the smallest gesture.
A compelling, thoughtful and thoroughly engaging show.
