Coast managing director Margaret McDonald is leaving the business.
McDonald will officially leave the womenswear chain at the end of July, Drapers has learned.
It is not yet clear what her next move will be, but it is understood she is relocating to the US with her family “to take up a new career opportunity”.
Derek Lovelock, former chairman of Aurora, will now step back in to oversee the retail business at Coast on a day to day basis alongside recently appointed deputy managing director Jo McWilliams and Pall Olafsson, chief financial officer.
There are no immediate plans to replace McDonald until Lovelock has assessed the needs of the newly independent management team.
Lovelock said: “Under Margaret’s leadership, Coast is starting to deliver its strategy of being the occasionwear specialist as evidenced by strong performance in the new flagship locations in Oxford Street, Trafford Centre and Leeds and supported by the online flagship and significant growth across Europe, Middle East and the US.
“Margaret leaves behind a strong senior team and we all wish her every success in this exciting new venture for her and her family.”
The move comes as plans are well underway to hive off the Coast chain from the former Aurora Fashions business to form a separate company with Oasis and Warehouse now under the separate control of new chief executive Liz Evans.
Karen Millen already operates independently.
