Leader of Brothers of Italy party Giorgia Meloni attends the fourth voting session to elect the new speaker, at the lower house of parliament, in Rome, Italy, October 14, 2022.
The Mussolini portrait will be taken down "to avoid polemics and manipulations," the industry ministry said in a statement.
The statement noted that another picture of Mussolini hangs in Palazzo Chigi, the prime minister's office, along with portraits of other Italian heads of government.
Earlier, former centre-left leader and industry minister Pier Luigi Bersani chafed at being hung alongside Italy's late dictator.
The public sector chapter of the CGIL, Italy's largest trade union, was also outraged, condemning the "deplorable" display and calling for its immediate removal.
