Whistles has appointed Phase Eight’s chief executive Ben Barnett and chief operating officer Lee Harlow as directors.
The appointments were made the day before Phase Eight’s owner The Foschini Group announced it had acquired Whistles on March 24, documents filed at Companies House show.
The South African firm bought a substantial majority shareholding in Whistles for an undisclosed sum.
The Foschini Group bought 85% of Poppy Holdco, which trades as Phase Eight, for around £140m in January 2015.
Jane Shepherdson is chief executive of Whistles.
