The Observer referred to analysis by The Grocer magazine which suggested that Tesco had admitted that it had suffered from availability problems.
The paper said that Tesco has axed 10 positions from its 20-strong board of supermarket directors as part of a drive to improve its supply and distribution network.
The losses include board members who were in charge of functions such as distribution, supply and communications.

The Sunday Express said that a £1bn deficit in Marks and Spencer’s pension fund could hit its profits due to be announced next month, according to M&S’ bankers Dresdner Kleinwort Wasserstein.
The retailer closed its final salary pension scheme to new members last year, but falling stock markets will mean it will have to use profits to boost the fund.
