Tesco is to create 1,500 new jobs in a major expansion in the Ireland.
It includes the opening of six new supermarkets by Tesco Ireland, and extension of several existing stores.
Of the new jobs, all of which will be in place over the next 12 months, 400 will be in an already-announced distribution centre in Dublin.
The development - part of a €100 million investment - was confirmed by Bertie Ahern.
Speaking at the presentation of the Tesco Irish Food Producer Awards in Dublin, Mr Ahern said: "These jobs bring good news to a number of locations throughout Ireland."
"Tesco will continue to be a major investor in Ireland, and the announcement today of new capital expenditure of over 100 million euros through this expansion programme is testament to their commitment as well as the future buoyancy of the retail market here."
