New figures on the Irish grocery market show that Tesco has reclaimed its position as the country's biggest retailer, having lost out to Supervalu in recent months.

The latest figures from Kantar Worldpanel show that for the 12 weeks to May 24, Tesco had a 25.2% share of the Irish grocery market, followed by Supervalu's 24.8% and Dunnes' 21.9% market share.

During the 12 week period, the number of visits to Tesco shops rose by 1.4% while the retailer also saw a spend increase of 0.5% from families with children.

But Kantar Worldpanel said that Tesco still has some ground to recover the 26.3% share of the market it had last year.

It also said that the battle for the top retailer spot will continue over the summer months, which are traditionally a strong period for Supervalu.

Kantar Worldpanel noted that Supervalu is the only retailer among the "big three" to consistently win new shoppers and it attracted 12,000 new customers over the 12 weeks under review.

Today's figures show that Dunnes posted the strongest sales growth of the three  big retailers with growth coming in at 4.1%.

This marked the company's sixth month of growth in a row despite some negative publicity in recent months.

The discounters - Aldi and Lidl - now hold a combined market share of 17%. Kantar Worldpanel noted that while both supermarket groups have seen their growth slow in the last number of months, the companies remain in a strong position.

"With shoppers paying 0.6% more for their groceries compared to last year, competition is fierce between the retailers as they battle it out to offer best value for money," commented Kantar Worldpanel's Georgieann Harrington.
