Department store retailer Debenhams has promoted Ross Clemmow as its new e-commerce director with immediate effect.

Clemmow joined Debenhams as divisional trading director of e-commerce in July 2013, and has overseen significant developments in its online proposition, including a site migration and an increase in emphasis on multi-channel.

"Online retail sales are increasingly important to Debenhams and in his new role, Ross will continue to develop our digital proposition and help support our strategy of becoming a leading international, multi-channel brand," said chief executive Michael Sharp.
