Ian Robertson, the chair of the Princess Royal Trust for Carers, has died, the charity has announced.
Robertson, 61, who was chair of the charity for three years, died suddenly on Monday. The cause of death is not yet known.
He became chair of the charity in September 2007 after retiring from HBOS, where he was managing director of corporate banking for eight years.
At HBOS, Robertson was involved in fundraising for the trust, including the bank’s Diamond Ball, which raised £1m for the charity.
Carole Cochrane, chief executive of the trust, said: "Ian’s passion for supporting unpaid carers and his wealth of financial experience meant that the trust was able to achieve its goals of generating funds for carers’ support and better influencing policy makers.
"Ian was also pivotal in stabilising and strengthening the trust during difficult economic times. On behalf of the trust we offer his family and friends our sincerest condolences during this sad time."
He leaves a wife, Valerie, and four sons.
