Online sales grew by six per cent in the year and the group said 75 per cent of total sales were completed online.
“A third of our website traffic is now generated from mobile devices and that figure continues to grow rapidly across all of our brands,” chief executive Alex Baldcock said.
“Looking ahead, we will start to see real incremental growth in sales from mobile as we continue to draw on our unparalleled knowledge of customer needs and shopping habits.”
