PARIS — Hermès chief executive officer Patrick Thomas has resigned from his role on the board of Lacoste SA, an Hermès spokeswoman confirmed.

Lacoste shareholders reelected their company’s board members on Monday, and the board subsequently named Sophie Lacoste Dournel as its president, a controversial decision contested by the previous president Michel Lacoste, her father.

The Hermès’ spokeswoman was unable to explain the motivation behind Thomas’ resignation, and it is unclear whether it was submitted at the shareholders’ meeting on Monday or since. Lacoste representatives were not immediately available for comment.

According to reports in the French media, Thomas and Lacoste’s two other external administrators, Danone’s Franck Riboud and former Chanel marketing director Micheline Kaufmann, had also been against Lacoste Dournel’s nomination and would have preferred to elect Marie-Beryl Lacoste Hamilton, who has more business experience and managed several of the brand’s licenses over the years.

Michel Lacoste, who has been at odds with his daughter for some time, has said he will take the case to court and accuses Swiss company Maus, which owns 35 percent of Lacoste, of trying to execute a covert takeover of the firm, the press reports said.

Various members of the Lacoste family own Lacoste’s remaining 65 percent.
