Art imitates life imitates art. The Thick of It returns for a new – and final – series this week, but the line between Armando Iannucci's political satire and the real-life Westminster village is becoming increasingly blurred.
"Omnishambles", the word that defined George Osborne's U-turn riddled Budget, was coined by writer Tony Roche for the show's Olympic-standard swearer Malcolm Tucker.
The first episode of the new series, which airs on Saturday on BBC2, sees the junior partner of a coalition government struggling to cling to its big policy idea, Silicone Playgrounds, which has echoes of Michael Gove's plan for children to develop mobile phone apps. "Sometimes you will invent a story," Iannucci said recently, "and someone will say 'how did you find out about that?'" This seven-part series, charting a coalition in crisis and an Opposition in the doldrums, also features a Leveson-style inquiry, a battle for the leadership and U-turns on U-turns.
Old faces return – Nicola Murray MP is now in opposition and, more worryingly, party leader – while Peter Mannion is now the cabinet minister for the Department for Social Affairs and Citizenship.
But Tucker remains the star, tormenting everyone in his path, thanks to the handiwork of the show's "swearing consultant", Ian Martin. Iannucci is uneasy about Tucker's hero-status: "Malcolm is representative of all that is poisonous and has caused so much disrespect for politics and politicians in the past 15 or 20 years. I don't understand people like Alastair [Campbell] who worship him."
Amazingly it's the politicians he feels sorry for. "I think most politicians want to make a difference," he adds. "They have a set of principles, ideals or ambitions, and I suspect the bulk of them stay like that."
As MPs return to stumble along Westminster's corridors of power this week, Iannucci's creation will seem painfully close to home.
