Forecasts in the retail sector predict that a food price war among the five biggest chains in Ireland is imminent.
The first major supermarket price survey in a decade shows variations of up to 50 per cent in the cost of own-brand goods.
Competition on price will increase in the coming months, with the big five fighting to keep or extend their market share, according to retail analysts Grant Thornton.
Stalker supposes that the emergence of a retail regulator will not happen quickly enough to obviate the subsequent tightening in prices for suppliers. The big five retailers in Ireland are Tesco, Dunnes, Aldi, Lidl and Supervalu.
