Tesco has refused to comment on reports that it is considering making a 1800m (£553m) bid for the Polish retail business of French retailer Casino. Reports have suggested that both Tesco and French retailer Carrefour are eyeing the business. Casino has already committed to selling 12bn-worth of its international assets by the end of the year in order to reduce its debts. Tesco entered Poland in 1995 and is the market leader there, operating more than 100 stores. A Tesco spokeswoman said: "We do not comment on rumour and speculation."

Carrefour has reported a 9.1% increase in second-quarter group sales to 121.4bn, boosted by improving sales in its French stores. The retailer said that like-for-like sales in France increased 3.6% excluding petrol in the quarter, helped by strong fresh produce sales. Total sales in the country increased 7.2% to 110.4bn, although like-for-like non-food sales fell 3%. Analysts said that improving sales in the retailer's domestic market were encouraging and showed "excellent momentum".

It also said that it had 3,900 stores in the US, where sales increased 10.4% to $33.1bn in June. US like-for-like sales increased 1.2%.

PepsiCo has reported a 13% increase in half-year net profit to $2.4bn on sales that have risen 11% to $15.8bn. The beverages giant said that its sales growth had been driven by sales of non-carbonated beverages, its snacks business and also by its health and wellness initiatives. PepsiCo chairman and chief executive officer Steve Reinemund said: "We are pleased with our performance for the first half of the year. Our balanced portfolio has been a key to the results we have achieved."

Russian supermarket chain Pyaterochka Holding has reported a 10% increase in second-quarter like-for-like sales. The retailer, which merged with its former rival, the Perekrestok chain, in May this year to create Russia's biggest supermarket group, said that like-for-like sales were up 7% in Pyaterochka stores and 14% in Perekrestok stores. It also opened 27 new stores in the period, bringing its total number of stores to 524.

Dutch retailer Ahold is selling 46 of its Tops Markets stores in north east Ohio. Ahold, which operates 119 Tops Markets stores, mainly in New York and Pennsylvania states, said that the decision had been made because the company no longer considered the region as a core area for the fascia. The Tops Markets stores are located in Greater Cleveland, Akron, Youngstown and Norwalk and employ approximately 3,800 staff.
