Here's how the supermarkets shared the grocery market for the last three months
It seems people are continuing to increase their spend on groceries.
According to Kantar Worldpanel, supermarkets have recorded a growth of 3.8% in the last 12 weeks up to the end of January.
It follows a similar increase in shopping over the course of Christmas.
The report says SuperValu has continued to attract most customers with 25% of the grocery market, up from 24.8% last year.
Dunnes enjoyed the strongest rate of growth of the top three supermarkets with sales up 5.1% compared with last year. To stand at 24.1%. Kantar said this is partly due to larger shopping trips where Dunnes saw shoppers spend an extra €1.70 on average every time they visit the store.
Lidl has seen double digit growth for the fourth consecutive three-month period to see them with 7.9% of the market, while Aldi, with 8% of the market, also posted a positive performance, with sales 2.9% higher than in 2015.
Georgieann Harrington, insight director at Kantar Worldpanel, said: "Tesco is still in second place, half a percentage point behind SuperValu, with a 24.5% share of the grocery market.
"However, sales growth of 1.1% makes this the most positive performance Tesco has seen since November 2012, so things are still looking up for the retailer."
