the Guardian reported on Thursday.De Koning’s study, which began in October, is co-sponsored by Historic Royal Palaces, an independent nonprofit that manages several monarchy-owned sites in London and Northern Ireland. Her research is due to wrap up in fall 2026.In a statement obtained by The Post, a spokesperson for Buckingham Palace said that the king takes this work “profoundly seriously,” repeating his message to Commonwealth leaders in Rwanda last year: “I cannot describe the depths of my personal sorrow at the suffering of so many, as I continue to deepen my own understanding of slavery’s enduring impact.”“That process has continued with vigor and determination since His Majesty’s accession,” the palace rep continued, adding that researchers would be granted access to the royal collections and archives.
