Retail giant Tesco has retained its top spot with the largest retail market share in Ireland, growing broadly in line with the market, according to the latest data from Kantar Worldpanel.

Figures published today (14 January) show Tesco held its market share at 27.8%, with sales growth of 0.9% for the 12 weeks to 23 December.

Dunnes managed to increase its supermarket share by 0.4% to 23.9%, behind Tesco, with sales growth of 1.9% – well ahead of the market growth rate of 0.3%.

“The strong performance of Dunnes comes after a prolonged period of under-performance, with market share hitting a low point of 21.4% in September,” said Kantar commercial director David Berry. “The boost in share over Christmas has regained some of this lost ground and places the retailer in a more competitive position for 2013.”

Elsewhere, SuperValu also both performed broadly in line with the market, according to Kantar, but its market share dipped slightly to 19.5% from 19.8%.

Continuing the trend, Aldi continues to post “exceptional” sales growth of 30% and its share has overtaken LIDL for the first time at 6% compared to Lidl’s 5.9%.

Aldi and Lidl achieved a combined 12.6% market share in October, with this dipping to 11.9% in the latest month.

Grocery inflation stood at 5% in the period, an increase on the 4.2% recorded last period and the highest since the 5.6% seen in May 2011.
