Dumbarton boss Jim Duffy has left the club after keeping them in Scottish League 1 via a play-off final win over Edinburgh City.
The experienced manager had been in charge at the C&G Systems Stadium since October 2018 when he took over from Stevie Aitken.
A statement on the club website said: "Dumbarton has parted company with manager Jim Duffy following the expiry of his contract. Discussions took place after a difficult season and it was agreed a new challenge would suit both parties.
"The club wishes to place on record its sincere thanks to Jim for his service as manager, especially during the recent unprecedented times, and all at the club wish him every success in the future."
