Hearing about the death of June Spencer at the age of 105 - who was in the Archers from 1950 to 2022 - made me curious as to the world record for longest time playing the same character

Depends on how you count: June started in 1950 but took some breaks for family, while Patricia Greene's Jill Archer started in 1957 and has a 67 year uninterrupted run
