PARIS, France — According to market sources, Delphine Arnault, the eldest child of LVMH chairman and chief executive Bernard Arnault, will leave her post as deputy general manager of Dior, which she has held since 2008, for a position at the group's largest luxury brand, Louis Vuitton, effective this September.

It is widely thought that Arnault will assume responsibility for the duties previously handled by Pietro Beccari, who departed Vuitton to take the reins as chief executive of Fendi in February, alongside other activities.

She will report to Louis Vuitton chief executive Michael Burke, who, along with Mr Arnault, has spearheaded an initiative to strengthen the positioning of the leather goods powerhouse at the top end of the luxury market.

Delphine Arnault is not the only one of her father's offspring to be appointed to executive-level positions at LVMH. Her younger brother Antoine Arnault, formerly communications director at Louis Vuitton, was tapped to become the chief executive of luxury men's brand Berluti in 2011.

Since 2003, Delphine Arnault has been on the board of directors at LVMH. As well as her tenure at Dior, where she began as commercial director in 2001, she has held senior roles at a number of other LVMH brands, including Loewe and Céline. She began her career at consulting firm McKinsey & Company and is a graduate of the London School of Economics and the EDHEC Business School in Paris.

BoF UPDATE: Wednesday 25 June, 1:45pm GMT: Michael Burke, chairman and chief executive of Louis Vuitton, has officially announced the appointment of Delphine Arnault as executive vice president of Louis Vuitton, effective in early September. "I am delighted to work again with Delphine Arnault," said Burke." I have had the opportunity to appreciate her human qualities and professional skills in the past. Her intimate knowledge of the universe of our high-quality products and her experience at the helm of one of the most prestigious houses in the group are key assets to contribute to the successful development of Louis Vuitton in the world."
