Queen's Park manager Ray McKinnon has left the club after steering them to the Scottish League 2 title in season 2020/21.
A club statement said: "While the decision will surprise many after gaining promotion to League 1 next season, the action had been agreed jointly to allow the club to begin the long-term task of restructuring once the initial aim of promotion had been secured.
"This will be aimed at delivering a new and innovative model in the Scottish game, rooted in our community and participation for all.
Chief executive Leeann Dempster added: “We are grateful to Ray for the work he has done, for leading the side to the League 2 title, and setting the club off on its journey in such a positive way. We wish him well.”
