The National Trust for Scotland looks for a new chairman
The National Trust for Scotland is to look for a new chairman after Sir Kenneth Calman announced he will step down in a year's time.
Sir Kenneth will have been at the head of Scotland's largest conservation charity for five years when he completes his term of office.
He will formally relinquish his role at the charity's AGM in September 2015.
Sir Kenneth said: "There is still much to do and I look forward to continuing to be part of a great organisation."
The current chairman took on the role in 2010 at what was described as "a time of significant change".
He said: "Over the past four years much has been accomplished thanks to the input of trustees, volunteers and staff, as well as local communities.
"The board has agreed a timetable for the creation of a new five-year strategy for the trust to be put before our members in 2016 and implemented from 2017.
"It is clear that leadership of the new strategy should therefore be from someone who can follow that process through and, for that reason, I am sure that next year is the right time for the trust to appoint a new chairman."
The trust's chief executive Kate Mavor said Sir Kenneth "will be a hard act to follow".
She added: "This is why we are allowing such a long lead-in time to appoint his successor.
"The board want to be confident they appoint the right person to take on the role, secure in the knowledge that Sir Ken's wise guidance and counsel will continue during this period."
