The Right to Rule describes Johnson as isolated on back benches, ‘scathing’ in private about MPs who did back him

Boris Johnson described his political allies as “The Munsters” and regularly hummed the Addams Family theme tune while discussing them after he quit as foreign secretary over Theresa May’s proposed Brexit deal, it has been claimed.

The former prime minister, who had returned to the Conservative back benches in July 2018, also joked that he had “cornered the market in sex pests” among his supporters, according to a book by the Telegraph’s political editor, Ben Riley-Smith.
