The new head of Seven West Media’s embattled newsrooms, Anthony De Ceglie, has a mandate to create a unified editorial voice when he takes over as Seven’s first combined editor-in-chief and director of news and current affairs on Monday.

Mr De Ceglie says he doesn’t do drugs. In that, he is like his new chief executive, Jeff Howard, who took over the ASX-listed media company last month and volunteered to Seven’s nearly 1000 journalists in an all-staff memo that he is a disciple of “call me boring” clean living – no cigarettes, coffee or illicit substances.
