Staff have completed a move from a weekly’s offices to a new base 30 miles away.
Two admin staff have been made redundant as a result of the closure, while two reporters have been transferred to the offices of the Chronicle’s sister title, the Ayrshire Weekly Press, in Ardrossan.
Editor Douglas Skelton has also left the Chronicle to pursue his career in writing.
Romanes has declined to comment on the closure.
However speaking in November, when the move was first announced, group publishing director Keith McIntyre said the move would “alleviate pressure” on journalists.
He added: “Romanes Media Group do not have a policy of closing local offices, in fact this year alone we have opened new offices in Slough, Reading and Dunfermline.
“However circumstances in Cumnock were different. The building itself required a great deal of work to maintain it and our editorial team was struggling to cope with absences whether for holidays or sickness.”
