Department store chain John Lewis has delivered a 4.8 per cent rise in like-for-like sales across the five weeks to Christmas, hitting £777m on the back of a successful advertising campaign starring Monty the penguin. In-store sales were flat, but this was offset by a double-digit rise in online sales of 19 percent. Click and Collect is proving particularly popular with shoppers with more now opting to pick up in-store than home delivery. Black Friday gave the retailer its single biggest sales week in 150 years.
