Cllr Tom Campbell said: “These are very sad circumstances. Their disappearance is deeply concerning.
“Our thoughts and prayers are with the wider family circle during this most distressing period.
“I would appeal to people to give police information as to the movements of couple in the hours leading up to their disappearance. Maybe someone has seen something, however small, and I would call on them to let police know as it may help them to find Robin and Margaret.”
