Design Museum co-directors Deyan Sudjic and Alice Black are leaving their posts at the London museum. A successor has been lined up and is expected to be named on Monday, Dezeen understands.
Sudjic and Black will step down in January 2020 after working together for 12 years, with Sudjic becoming director emeritus.
The museum appointed headhunters earlier this summer to recruit for a replacement, which will combine the roles of chief executive and director. Until now the museum has not had a chief executive.
The new chief executive and director is expected to be announced on Monday.
Sudjic and Black oversaw the Design Museum's 2016 move from its premises in Shad Thames to its new home in the former Commonwealth Institute on Kensington High Street. Pair moved Design Museum to new home
Sudjic was appointed director in 2006 and devised the strategy for the Design Museum's expansion that would offer free admission for the first time. Black joined as deputy director in 2007 to lead the move to the institution's new premises.
Black became co-director of the museum a month after the move into the John Pawson and OMA-designed building was completed in 2016.

"Having established the Design Museum in its new home, after record visitors this year, I am now ready for a new challenge," said Black.
"We have shown that design can change the world, and that the Design Museum has changed design. Now I want to see where design is going next," added Sudjic.
