We're devastated to share this news.
Nick was a fantastic trainer and a wonderful person. He was funny, witty, and he lit up every room he was in.
He will be sorely missed by us all.
"Nick has been a wonderful colleague. He was a hugely talented journalist, presenter and author – and one of those rare people who light up the lives of everyone around them."
Head of News and Current Affairs at BBC Scotland Gary Smith pays tribute to Nick Sheridan.
