Online retailer Zalando is planning an own-label division as a standalone business as it attempts to tap untapped markets and challenge rivals.

The German-based etailer‘s own-labels chief Jan Wilmking predicted the own-label business would grow between 20 and 25 per cent every year – a similar rate to the rest of Zalando.
