The figures for the 12 months to the end of July put its share at 21.8%, down from 22.2% the previous year. In 2001 its share peaked at 23.5%. Dunnes’ big rival Tesco has improved its market position in the same period, with its share rising from 23.9% to 24.4%. Superquinn has slipped slightly, from 8.6% to 8.5%. The SuperValu chain shows a marginal improvement, from 19.3% to 19.4%, with Centra increasing from 2.6% to 3.2%.
But a spokeswoman for the Musgrave-operated groups claimed their combined market share was much higher, as the survey did not adequately reflect c-store sales.
However, discount chains Lidl and Aldi reported a significant advance, with their combined market share increasing from 4.2% to 5.4%.
