The episode opens with newsreel coverage of the King David Hotel bombing in Jerusalem on 22 July 1946, which acts as a background to later tensions over the Palestine issue in London. References are also made to graffiti depicted symbolising Perish Judah ("PJ"), and a Right Club type of organisation which agitates Londoners in Adam Wainwright's electoral district. The show also references the early stages of the formation of the NHS.
