Tesco has regained the title of Ireland's biggest grocery retailer from SuperValu - but the glory is likely to be short-lived.
The latest figures from research group Kantar Worldpanel show that Tesco now controls 25.2pc of the multi-billion euro Irish grocery market. Supervalu, which is controlled by the Cork-based Musgrave group, has a 24.8pc share.
The data is for the 12-week period to May 24. The previous figures had Tesco and SuperValu neck-and-neck with 25pc each, but prior to that SuperValu had clinched the top spot. It had been the first time in over a decade that Tesco wasn't Ireland's biggest grocery retailer.
While some industry insiders question the market share figures, they are nevertheless based on surveys of the shopping habits of 3,000 households around the country.
It's also likely that Tesco and SuperValu will continue to alternate the top spot in coming months, as they vie with each other to be the country's biggest grocery chain.
SuperValu traditionally performs well over the summer season, while Tesco does well as parents prepare for children returning to school.
The figures also show that Dunnes Stores performed strongly in the latest period. It saw a 4.1pc rise in the value of its sales, giving it a 21.9pc market share. That's despite industrial action by Dunnes workers who've been calling for better pay and conditions.
Georgieann Harrington, insight director at Kantar Worldpanel, said that although Tesco has regained the number one position, it is still experiencing sales declines as its performance remains behind the overall market.
