Spencer Feeney, editor of South Wales Evening Post and editor-in-chief of South West Wales Media, is to retire in September 2012 after 10 years.
Mr Feeney started in journalism as a trainee reporter at the Post after leaving Dynevor Grammar School in 1969.
He has been editor of the South Wales Evening Post since 2002. Before that, he was editor of The Citizen, Gloucester. He was appointed to his first editorship, the Llanelli Star, in 1986.
During his editorship, the Post overhauled Cardiff-based titles the Western Mail and South Wales Echo to become the largest-selling regional newspaper in Wales.
Additionally, South Wales Evening Post has promoted Helen Keates from politics reporter to assistant news editor, replacing Alex Brown who has moved to another department.
