The Group's online business now accounts for 56% of its £1.6bn total sales, up from 18% three years ago. Shop Direct has around five million active customers shopping across its broad portfolio of brands in the UK.

The Brooklyn Brothers and Glue London have taken on the advertising and digital accounts for the relaunched Woolworths brand.
