The profit fall is due to Morrison's £3bn takeover of rival Safeway, a move which has turned out to be a hard dish for the company to swallow.
The profitability fall could mean further pricing pressure on the company's food suppliers, who have seen their margins decline as retailing power increases in the market. The UK's competition regulator is currently investigating that buying power to see if it is unfair.
The company yesterday announced plans to boost margins, reduce staff and save £60m on costs.
Morrison is is in a vicious battle for market share with the top three retailers in the UK.
Morrision holds a 12.5 per cent share of the UK's retail market according to the latest figures released yesterday by TNS.
Tesco holds a 29.1 per cent share, Asda a 16.8 per cent share and Sainsbury's a 16 per cent share.
Morrison yesterday reported the loss for the 12 months to 29 January, a result of £374m in one-off costs and write-offs. Profit for the year totalled £61.5m compared with £332m a year ago.
Profit before tax, Safeway conversion and integration costs and goodwill written off, down from £332.2m to £61.5m.
The company's net debt currently stands at £1.15bn.
