The department store retailer posted a 2.5% fall in sales in the week to January 25, exacerbated by a 9.3% slump in sales across its home division during the period.

The retailer’s electricals and home technology sales rose 1.1% year on year, driven by operating system Windows 7 reaching its end of life and triggering new purchases of computers and laptops. Fashion sales also edged up 0.4%, while beauty, well-being and leisure sales increased 1.4%.

Sister retailer Waitrose posted a 1.6% decline in sales.
