Supermarket price war is 'brutal'
The supermarket chain, Morrisons has reported a fall in underlying sales for the three months to the end of April.
Like-for-like sales, which ignore new store openings, fell 1%.
However, total sales were up by 1.5%.
Morrisons said the economic environment for the consumer had "remained challenging".
Adam Leyland, editor of The Grocer Magazine, told the BBC that the supermarket chain was struggling against other "downmarket" supermarkets like Aldi.
