- Tesco's overseas businesses, such as its European, Asian and US ventures, will weigh on the overall group performance.
- Analysts have predicted a slide in profits as a variety of economic and political issues slow sales in Poland, the Czech Republic, Hungary and South Korea.
- Sunday trading restrictions in Korea have hit the business there hard and could be behind a slide in Asian profits of around 5%, while high tax in Hungary will be one of the reasons behind a 10% drop in profits in the European region.
- And Tesco is likely to come under further pressure over its troubled US chain - Fresh & Easy - as it continues to report losses and moves to cut costs.
Tesco’s profits have dropped for the first time in almost two decades while Sainsbury has squeezed out a rise in profits.
Today Tesco, Britain's biggest supermarket chain, is expected to announce its first profit fall in almost twenty years.
