The writers appear to be fans of DC Comics. As stated above, the delusional British PM and his ministers don DC superhero garb; his caped white whippet 'Krypto' is hurled to its doom from a 10 Downing Street window for its "fly around the block"; semi-generic Superman adventures and specific characters (e.g. Doctor Destiny) are frequently mentioned (The best known example is probably, "Can't make Prime Minister's questions, Brainiac has escaped from the Phantom Zone") ; an Iranian mullah is mentioned to have "dressed as Aquaman"; Ed Bishop's character 'Jay Garrick' has the same name as the Golden Age Flash; and the elderly American farming couple held by the Soviets are named "Jonathan and Martha" which are the names of Superman's Earth parents in current DC continuity.
