Although heavily modified, the series bears close resemblance in the overall arch of an infiltrated government official, the web of double crosses concerning military industry, its highly nationalistic tone and even title, to Verräter (1936), a German propaganda film produced by the UFA under Joseph Goebbels. The movie is now considered (despite its original use) a thriller masterpiece, and became the highest grossing film in Europe, winning several awards.
When the new Labour MP gives his maiden speech, he is met with boos and cheers. In fact, the tradition is that maiden speeches are all heard in respectful silence and are not meant to be party political.
In 1945, a maiden speech in the House of Commons was expected to be respectful, polite, and non-controversial, paying tribute to the predecessor, expressing humility, and focusing on constituency issues. The speech would highlight the MP's dedication to public service, avoid partisan conflict, and demonstrate respect for parliamentary traditions and senior members. The speech by Hugh Fenton MP in Traitors simply would not have happened.
