Archie Campbell from North Uist, a former teacher, was first elected to Comhairle nan Eilean Siar in 1999 and served as chair of the sustainable development committee from 2003 to 2014.
Mr Campbell said: “It has been a great privilege and a wonderful experience to serve the local community as an elected member of Comhairle nan Eilean Siar over these 15 years.
“It has also been a pleasure to work with my colleagues in the ward, Cllrs Uisdean Robertson and Neil Beaton and I wish them every success in their continuing role in the council.”
Comhairle convener Norman A MacDonald commented: “Archie enjoyed a long career as a teacher, starting at Paible school in 1967 before moving to Iochdar and then to Lionacleit in 1988 where he served as the Principal Teacher of Guidance. He retired in 1997 and is a Fellow of the Educational Institute of Scotland.
“Archie served the people of North Uist and Benbecula well during his time on the comhairle and he also served the people of the wider Western Isles in his role as vice-chair and then chair of the Development Committee.”
He added: “Archie will be remembered during his time as a councillor as someone who would weigh up the arguments of a particular discussion, reach a decision and stick with that decision.
“He always did so with good humour and respect for his comhairle colleagues. Archie has had a long, successful professional and political career and he now deserves to enjoy more time with his wife, Ada, and their children Eilidh, Sarah and Alasdair and their six grandchildren.”
