Tesco is re-opening some of its stores in the border counties of the Republic of Ireland with marked-down stock reflecting sterling prices in an effort to curb customers crossing the border to buy their groceries in Northern Ireland.

Tesco closed 11 of its stores over the bank holiday weekend and will reopen them with a larger range of cheaper goods with more imports from the UK.

The move could be repeated in all of its 116 Irish stores but Tesco has denied it will phase out Irish goods altogether.

The supermarket giant had been losing out with shoppers going over to Northern Ireland, where there is a stronger presence from competitors including Asda and Sainsbury’s.
