Kering, which derives the biggest chunk of its earnings from mega-brands like Gucci and Saint Laurent, bought a 51 percent stake in Christopher Kane in 2013.

The group, which is focussed squarely on luxury after spinning out German sportswear brand Puma to its shareholders earlier this year, did not disclose financial terms around a possible buy-back by the Scottish-born designer, known for his fashion-forward, edgy creations.

Fellow British designer Stella McCartney is also in the process of buying back the 50 percent of her brand owned by Kering, following a 17-year partnership.
