When Lambton was interviewed by MI5 officer Charles Elwell, Lambton first claimed that the pressure of his job as a minister was what drove him to procure the prostitutes. Later, Lambton stated that his sense of "the futility of the job" and lack of demanding tasks as a junior minister were reasons he went to prostitutes. Finally, Lambton claimed that his judgment was faulty when he went to the prostitutes due to his obsession with the battle over the use of an aristocratic title that had been used by his father; Lambton claimed that he sought to soothe this obsession by engaging in frantic activities such as gardening and debauchery.
