After 12 devoted years on the club’s board, Kane has relinquished his position due to increased commitments.
He said: "A combination of personal and family travel commitments, coupled with a significant increase in workload in certain other charitable responsibilities, has meant the time I can devote to club matters is below the level at which I believe I can make a contribution that I would feel was appropriate and meaningful.
"At the same time I am also of the opinion that after over twelve years as a director of the club, it is an opportune time to step down and allow the next generation of leadership to have their time at the helm.
"My family and I have thoroughly enjoyed our links with the club and hope to continue supporting the Blues for many years to come. Some of our most memorable moments over the past 20 years have involved the football club and the people concerned.
"I am, of course, always available to offer advice and assistance in any way I can and look forward to maintaining on-going close ties with the club in whatever capacity in the years ahead."
Director Matt Clarke said: "On behalf of the club, I would like to thank Brian for his efforts over the years. He’s put in an awful lot of work that has gone unnoticed, but has undoubtedly made a significant contribution to the club.
"He’s been a valuable member of the board and knows he is very welcome to come back to Adams Park anytime he wishes."
