Waitrose has reported full-year like-for-like sales growth of 3.6%, excluding petrol.

Operating profit, for the year to 26 January, rose 22% to £212.1m, on sales up 6.8% at £3.95bn.

Sales at the supermarket chain had increased 47% in the past four years, said Charlie Mayfield, chairman of parent company John Lewis Partnership.

It now has a 3.9% share of the grocery market, with an 18% share in the UK organics market and an 8.6% share in the Fairtrade market.

“While we expect trading conditions to continue to be challenging in the year ahead, we are confident that the diversity of our business and our partnership model makes us resilient and able to perform well even in the most testing market conditions,” Mayfield added.

“We are committed to the growth plans for our business and I am confident that we can deliver our long term plans.”
