Every time a supermarket opens, local services close. And Tesco now controls 28% of the grocery market.

"We entered Ireland in 1997 with the acquisition of Associated British Foods' Irish retail operations, better known as the Quinnsworth and Crazy Prices retail chains. Our business has since grown to become the leading grocery retailer with 146 stores across the country."

The sourcing of products is a further problem. According to Wikipedia;

Tesco tried to hide its policy of buying directly from UK suppliers from Irish people. An internal document said that ensuring its policy of taking deliveries directly from UK suppliers went unnoticed and "invisible to the Irish customer" was a key objective.

At the same time the Irish Farmers' Association president said there was deep anger about Tesco's decision to displace local produce with imports "will inevitably lead to thousands of job losses and will put Irish producers of local, fresh produce out of business."
