Mark Mortimer has stepped down as head teacher or ‘warden’ at Glenalmond College, The Courier has reported.

Last month 35 Education, a British-based philanthropic education enterprise, took over The Glenalmond Group, which encompasses Glenalmond College.

Mortimer announced his departure in an open letter to parents as pupils broke up for the summer holidays.

Executive principal of the Glenalmond Schools Group, Lucy Elphinstone, has taken on the role of ‘acting warden’.

A Glenalmond College spokesperson said: “It was mutually agreed that Mark would step down from his post following completion of the partnership, to allow the new chapter to begin.

“Mark worked closely with the board and 35 Education, helping to secure a sustainable future for Glenalmond, and is now very much looking forward to seeing how this will develop.

“We are delighted that Mark will continue to be a part of the Glenalmond community, as an invested parent [Mortimer’s three children attend the school] and we look forward to seeing him at events over the course of the school year.

“After a number of years in post, Ian Gray, chair of the Glenalmond Schools Group board of governors, has also stepped down, after serving his full time in office, staying on longer for the partnership to complete.”
