In his forthcoming book 'Unleashed,' former British Prime Minister Boris Johnson alleges that a listening device was discovered in his personal bathroom at the Foreign Office after a 2017 visit by Israeli Prime Minister Benjamin Netanyahu. Johnson claims that Netanyahu used his bathroom, and during a subsequent bug sweep, a listening device was detected. While Johnson implies Israeli involvement, revealing little beyond the book's content, no official comment has been made by the Israeli government or the Foreign Office regarding the incident. The allegations add to past suspicions about Israeli espionage activities, including claims of cell phone surveillance devices around the White House in 2019. Johnson's memoir, which also touches on other sensitive issues, is scheduled for publication on October 10.
