The potential hook up between Sainsburys and Asda has caused quite a flutter in the UK supermarket sector.
So big would it be that even Bord Bia are setting up a study to look at the effects of such a merger on the buying power of the new entity.
Suppliers to the chain would find it harder to negotiate good terms when the company would wield such buying clout.
The supermarket group promised that shoppers would see a 10 per cent cut in price of popular foods as a result of the merger. You can be sure that consumers will like that.
