Shetland South member Billy Fox has resigned today from his position as deputy leader of Shetland Islands Council.
Mr Fox, who was elected to the SIC four years ago as the three members of his constituency along with Allison Duncan and George Smith, took on the deputy leader post in May 2014.
Before becoming a councillor he was a long-time critic of the Viking Energy windfarm, and was chairman of anti-Viking protest group Sustainable Shetland.
He said: “My resignation does not stem from any major difficulty within the council; this is one of the best and most responsible councils we have ever had.
“However, there are some issues of policy and process which I do have concerns with, on occasions I would like to comment but find myself restricted in my role as deputy leader.
“At this moment I do not wish to comment further however in the fullness of time and should I feel it necessary I will be free to air my concerns.
“I have not made this decision lightly and I remain fully committed to the good work this council has done and continues to carry out.
“I still look forward to spending the final year of this council in a fully active back-bench role. I will still sit on more committees than most.”
