All eyes are on Tesco this week as investors wait for the retail giant to release its trading update tomorrow.

Analyst Shore Capital is predicting Tesco to reveal like-for-like sales growth of between 5 and 5.5% for the seven weeks to January 7.

And Dresdner Kleinwort Wasserstein is expecting Tesco to report an 11% increase in UK sales and a 21% increase in its international sales. Overall, Tesco is expected to reveal total sales of 14%.

Despite upbeat figures, Tesco continues to face a backlash from campaigners concerned about its growing dominance of the grocery sector, of which it has a market share of more than 30%.

A report by environmental campaigner Friends of the Earth claims that there is a growing trend for supermarket groups, including Tesco, to flout planning restrictions.

Simon Webster, from Friends of the Earth, said: “The planning process is structured to help supermarkets get their planning permission. Examples of where Tesco has ignored terms of their planning consent are not just isolated incidents but a pattern.”
