Peter is one of the best-known voices on radio in Wales, and currently presents Good Morning Wales on Saturdays.
Peter has been covering Wales and the world for BBC Wales since the late 1970s. Currently, he can be heard presenting Good Evening Wales and occasionally be seen as a television reporter for BBC Wales' current affairs series Week In Week Out.
Before presenting Good Evening Wales, Peter had a long association with Eye on Wales. He was the presenter of the investigation into a miscarriage of justice known as the case of the Gurnos Three, which won a BT Welsh Press Award for the programme in 1999.
After taking a degree in politics at the University of Exeter, Peter Johnson trained as a journalist on his local paper - the Pontypridd Observer.
He then spent a year on the Western Mail before moving into broadcasting with the BBC Wales news team in 1977.
Peter worked as producer and reporter in television and radio news and began daily radio presenting on the drive time programme 456.
Later he moved into the presenter's chair for the breakfast slot, as a stand-in for the departed Chris Stuart. A six-month temporary job turned into a 12-year stint, fronting both Weekday Wales and its successor Good Morning Wales.
Peter is married to Jean and they have two adult daughters. His hobbies include watching his hometown rugby team, films and jazz.
