Somerfield is likely to unveil a strong first quarter trading performance - due in part to the hot summer - at its agm in Bristol on September 3.

Last full-year like-for-like sales growth at the supermarket group was 1% but analysts said this figure had probably doubled over the last quarter.

One analyst said the weather had helped and Somerfield was likely to mirror the good figures at Asda and Waitrose.

Mark Hughes at Numis Securities believed Somerfield was trading reasonably well. “Looking at TNS data we expect a like-for-like sales growth figure of about 2% to 2.5%.” However, he said executive chairman John von Spreckelsen had not defined clear growth targets.
