The move was led by Sally Osman, who was previously press secretary for Prince Charles and was promoted to lead the operation as director of comms. The merger was the first time in a generation that all the royal family’s comms teams were working together in the same office.
However, after a trial period Prince Charles' press team has now returned to Clarence House.
The comms team for Prince William, Kate and Harry, formerly based in Kensington Palace, will continue to operate from Buckingham Palace, under Osman, with James Roscoe as the Queen’s press secretary.
Clarence House will initially be led by Kristina Kyriacou until a successor for Patrick Harrison, who is leaving after 14 years to join Weber Shandwick in the New Year, is found.
Kyriacou is transitioning into a new role where she will take on private clients as well as handle some of the media relations for Clarence House.
The news of Harrison's departure followed that of Ed Perkins, the press secretary to Prince William, Harry and Kate.
Perkins is taking up a senior adviser role at Portland and the recruitment process for his replacement is currently under way.
