Findings to come as supplier probe continues

The Competition Commission is understood to be set to release provisional findings from its investigation into the£120 billion-a-year grocery sector next month, despite a new probe into Tesco and Asda’s supplier relationships.

The commission is to trawl through millions of e-mails between Tesco and Asda and their suppliers. It ordered Tesco and Asda to disclose all correspondence with their suppliers over a five-week period in June and July.

It is thought that the commission received allegations that the chains had acted in a “threatening and aggressive” manner in demanding discounts on goods.

The other two supermarkets of the big four, Sainsbury’s and Morrisons, have not been issued with section 109 notices, which override issues of confidentiality.
