The chief executive at Brighton & Hove Museums is to step down after six years in the role.
Hedley Swain will leave at the end of October because he is relocating to Sweden with his wife, who is taking up a museum position in Stockholm, the charity said.
The charity, which runs museums including the Royal Pavilion and Brighton Museum & Art Gallery, said Swain led the charity through a “pivotal period of change,” as it became an independent charitable trust.
He also “helped secure millions of pounds of investment in buildings and collections”, the charity said.
Michael Bedingfield, chair at Brighton & Hove Museums, said: “I want to express our deep gratitude to Hedley for his dedicated leadership over the past six years.
“Hedley has steered the trust through significant challenges and opportunities with steady vision, deep sector expertise and genuine passion for our cultural heritage. He leaves the organisation in a strong position for the future.”
Union members at the charity were set to strike between 3 and 5 June following two days of industrial action in April and ongoing disputes over pay. An agreement was reached on 4 June, halting the strike action.
“It has been an exceptionally busy six years, and I have loved being in Brighton and I am immensely proud of all we have achieved together,” said Swain.
“I wish the trust every success on its ongoing journey and look forward to watching its progress,” he said.
Abigail Thomas, the charity’s deputy chief executive, will become interim chief executive in October until a permanent successor to Swain is found.
