Edward Montebello has been appointed head of communications of the Office of the Prime Minister, moving on from his post as head of One News.
A graduate in history and education, Montebello worked as a teacher before taking up journalism 18 years ago.
The Office of the Prime Minister thanked Matthew Carbone, who was the previous head of communications.
