Liverpool’s International Slavery Museum has cut ties with the company run by Sir David Adjaye but it will still use his design for its redevelopment.
Adjaye Associates had led the architectural design of the museum’s £57m plans.
It follows reports in the Financial Times (FT) three women had accused Sir David of sexual assault and harassment.
BHe has previously denied the allegations.
Three women, all previously employed by Sir David, have accused him of different forms of “exploitation”, the FT said, and have claimed their dealings with him had disrupted their careers and caused serious mental distress.
Earlier this year he admitted he had “entered into relationships which though entirely consensual, blurred the boundaries between my professional and personal lives,” adding, “I am deeply sorry”.
