SUPERMARKETS SuperValu and Tesco have 25pc market share each and are tied in first place, according to the latest figures from Kantor for the 12 weeks ending April.
"Over the past 12 weeks SuperValu and Tesco have each captured 25pc of the grocery market, with SuperValu battling to hold on to the number one position it claimed last month and Tesco aiming to recover lost ground," said David Berry, director at Kantar Worldpanel.
Among the big three retailers, Dunnes has posted the strongest sales growth of 3.6pc, lifting its market share from 21.5pc to 22pc.
Dunnes has been benefiting from an offer that gives hefty discounts to customers who make big purchases.
It wasn't good news for everybody.
"One of the most interesting trends in the latest data is the slowing growth rate of both Aldi and Lidl," he added.
"While the 8.8pc growth posted by Aldi and 7.8pc for Lidl remains impressive, this is the first time since 2010 that both Aldi and Lidl have grown their sales by less than 10pc."
