The adaptation ‘Secret State’ diverges significantly from Chris Mullin’s original novel, with major changes to the main character’s background, the political context, and the narrative’s central focus. While the book centers on Harry Perkins, a left-wing Labour Prime Minister, the series introduces Tom Dawkins, the Deputy Prime Minister, navigating the aftermath of an industrial disaster. This shift not only changes the character’s motivations but also reframes the political allegiances and stakes at play.

In contrast to the novel’s Cold War context and its overt leftist politics, ‘Secret State’ opts for a modern setting and downplays class struggle and overt socialist policy. It instead places emphasis on corporate corruption, terrorism, and contemporary fears around big business manipulating government, altering the sense of historic urgency present in the book.

Another notable difference is the tone and resolution. Mullin’s novel is imbued with an element of idealism, portraying Perkins as fighting against a corrupt establishment against all odds. The TV adaptation, however, adopts a darker, more cynical approach, where the machinations of the elite and the impotence of principled leaders feel even more pronounced, offering a less hopeful outlook.

Furthermore, the plotlines largely diverge after establishing their basic conspiratorial premise. Key characters and events from the novel are either reinvented or omitted altogether; for example, the way the political crisis escalates and resolves is handled very differently in ‘Secret State’. This results in a viewing experience that feels inspired by, rather than directly based on, Mullin’s original work.

Chris Mullin’s ‘A Very British Coup’ delivers a razor-sharp, immersive political narrative that lures readers deep into the heart of Westminster. The novel’s detailed depiction of British bureaucracy, power games, and machinations offers insights and suspense that the screen version only hints at. Mullin’s prose enables readers to inhabit the inner world of its principled protagonist, unmasking the complexities of ideals versus the ruthless realities of high office.

Unlike the TV series, the book invites genuine intellectual engagement, raising timeless questions about democracy, corruption, and personal integrity. Readers are encouraged to question not just the narrative, but their own beliefs about leadership and the media’s influence over public perception. Mullin’s thoughtful explorations and empathetic characterization make for a richer, slower-burning but ultimately more rewarding experience.

Reading ‘A Very British Coup’ allows you to see past the cinematic polish and delve into the political anxieties of the era it was written, which still resonate today. The novel’s depth and nuance reveal layers of meaning that adaptation cannot capture, offering a more personal and profound perspective on the perils of power.

Secret State explores the relationship between a democratically elected government, big business and the banks.

Drama

A Very British Coup

Secret State

The TV series is faithful to the novel’s central premise—a left-wing prime minister besieged by the British establishment—but condenses timelines and merges roles to fit three episodes. This streamlining shifts the balance from the book’s broader political canvas toward a taut, event-driven thriller.

On screen, the intelligence and media antagonists are sharpened into clearer figureheads and clandestine cells, while the novel spreads responsibility across a wider ecosystem of mandarins, backbenchers, proprietors, and fixers. The book lingers on party democracy, trade-union dynamics, and parliamentary procedure in ways the adaptation necessarily compresses.

Policy and plot details are simplified for pace. The series trims aspects of nationalization battles, anti-nuclear policy wrangling, and internal Labour disputes that the novel explores in granular, often witty detail. Readers will find more backstory, more institutional texture, and a fuller sense of how press briefings, leaks, and deniable operations accumulate into a “soft” coup.

The tone and finale differ notably. The novel’s conclusion is starker and more definitive about the cost of confronting entrenched power, whereas the series closes on a more ambiguous, suspense-driven note. On the page, Mullin’s sardonic commentary and access to Perkins’s inner life deepen motivations and moral stakes in ways the camera—by necessity—renders through implication and atmosphere.

Before you stream the TV series, discover the original power and precision of Chris Mullin’s A Very British Coup. Written by a journalist-turned-MP, the novel delivers insider credibility, razor-sharp politics, and a chillingly plausible portrait of establishment pushback against democratic change.

On the page, Harry Perkins’s ideals, doubts, and strategies unfold with a depth only a novel can provide. Mullin’s nuanced satire, rich policy detail, and sly humor illuminate the media storms, intelligence intrigue, and parliamentary knife-fights that shape every twist of the plot.

If you love political thrillers like House of Cards or state-of-the-nation sagas with real-world bite, read the book that started it all. A Very British Coup is widely available in paperback, ebook, and audiobook—essential reading for anyone who wants the unfiltered, definitive version of this story.
