Dunnes, SuperValu close Tesco gap

Latest grocery market share figures show that Dunnes was the big winner over the past 12 weeks, while SuperValu has almost drawn level with Tesco as market leader.

The data from consumer insights agency Kantar Worldpanel cover the three months to the beginning of March. They show a healthy combined year-on-year 2.4% rise in sales for all the big supermarket groups.

However, on an individual basis, the big mover has been Dunnes, which increased its market share by over 1% on the same period last year, to stand at 23.4%, and which saw a 6.5% jump in the value of over-the-counter sales, helped largely by its recent ‘shop and save’ campaign.
