Tesco is expected to provide the City with an update on its first-quarter trading on Wednesday (14 June).

Earlier this year the retail giant reported a 16.7% increase in group pre-tax profit to £2.21bn, on group sales up 13.2% to £41.8bn.

However, it also reported a slowdown in sales in the final quarter of the year, with like-for-like growth of only 4.9%.

As a result, analysts are expecting Tesco to record like-for-like sales growth between 4.5% and 5% for the 13 weeks to 27 May.

They have also predicted a 7.5% increase in total sales and a 25% increase in international sales.

However, there are concerns that Tesco is feeling some of the brunt following recent improved performances from Sainsbury and Morrisons.

It has also failed to take the crown from Asda as the UK's cheapest supermarket.

In this week's issue of The Grocer, Asda topped The Grocer 33 - an independent survey of grocery prices, customer service and availability conducted by The Grocer, for the ninth successive year.

However, Tesco is gaining ground and its average basket price for the year is currently just 0.7% more expensive than Asda's, according to The Grocer 100 basket survey, which tracks the price of a secret 100-item basket of goods at each of the six major multiples.
