Tesco is expected to report a 12% increase in full-year pre-tax profit to a record £2.5bn tomorrow (Tuesday).

Full-year sales are also expected to increase 10% to more than £42bn.

However, analysts are concerned that Tesco has not matched the recent sales growth of rivals Asda and Sainsbury's and its like-for-like sales growth excluding petrol could have fallen to “its lowest level in years”, according to Citigroup.

Analysts will also be eager to hear how the retailer is faring in international markets with concerns over recent economic and political turmoil in Hungary, Thailand and South Korea, where Tesco operates.

They will also be interested to see how its non-food catalogue Tesco Direct, launched last year, is faring as well as further news on the imminent launch of its US convenience chain format Fresh & Easy.

Last week, a shop workers union in the US sent thousands of flyers to homes in Phoenix, Arizona, suggesting that Tesco sells alcohol to minors, according to The Independent.
