One of the local authority building control officers tasked with overseeing the refurbishment of Grenfell Tower quit his role weeks before 2017’s fire because he “had enough” of not being able to do his job in the way he felt it should be done, the probe into the disaster has heard.

John Hoban told the Grenfell Tower Inquiry today that he had worked for the Royal Borough of Kensington and Chelsea for almost three decades after starting his career as a junior technical officer at the Greater London Council in the 1970s.
