Tesco regained its place as Ireland's most popular grocery retailer last month after being knocked off the top spot by Supervalu in April.

However, Tesco has suffered a decrease in shoppers and spend with a sales decline of 3.3% though there has been a year-on-year growth in sales of 0.9% across the market.

With a share of 24.7%, SuperValu sales grew at 0.6%. Some 19,000 fewer shoppers visited the retailer than over the same period last year.

The figures, published on Monday for the 12 weeks ending 21 June, show that Dunnes Stores increased sales by 6.3% to achieve a market share of 22.2%, up from 21% in the same period last year. This success has been attributed to the retailer's ‘Shop & Save’ voucher scheme, which has seen the average Dunnes visitor buying 18 items per trip compared with a market average of 13.

The discount retailers also performed strongly and Lidl experienced the highest growth of all the grocers at 6.4%. However, the growth in new shoppers is slowing. Aldi gained 28,000 new shoppers in the past 12 weeks compared with 80,000 this time last year, while Lidl welcomed 6,000 – down from 53,000 in the 12 weeks to June 2014.
