Canary Wharf Group chief executive George Iacobescu is to add chairman to his responsibilities following the retirement on Thursday of Sir Martin Jacomb.
Jacomb has been a director of Canary Wharf Group since 1999, including the past seven years as chairman.
He said: “During my 12 years on the board, Canary Wharf has almost trebled in size and has proved an outstanding success. I am confident that the company is in safe hands and is well positioned to deliver further development and growth.”
