Figures for the 12-week period to 19 June show continued growth in the grocery markets, with sales rising by 2.5% compared to last year.

The increase is shown in Kantar Worldpanel's latest cache of figures, which indicates an increase in household spending of €27 this year.

With the exception of Tesco, all of the major retailers increased sales over the period, with Dunnes Stores posting the strongest performance and growing sales by 5.9%.

The retailer attracted an extra 13,000 shoppers to its stores this year with the average spend increasing by almost €20.

Lidl posted the second highest sales growth – 5.8% – which was mainly the result of attracting an additional 55,000 shoppers.

Aldi sales grew by 3.6% in the latest quarter, with the discounter also recruiting an impressive 37,000 customers versus last year.

However a combination of flat shopper numbers and only marginal increases in average spend mean Aldi continues to lag behind it's German rival.

SuperValu retains its position as Ireland’s largest retailer, growing its sales by 1.4% and capturing 22.6% of market share.

Despite failing to increase sales, Tesco remains the second most popular retailer with 22% of the market share, a 2.7% decline since the same period last year.
