The Co-operative Group is extending its Truly Irresistible premium range with products focusing on the summer barbecue season.

About 20 new condiment, barbecue meat and soft drink products have been added including an Aberdeen Angus burger with cheese and a salmon, lemon & coriander burger.

Other new lines include a tomato & chilli chutney and sparkling elderflower, blackcurrant and raspberry drinks. An English Apple Crush is made from fruit grown at The Co-op's farm in Herefordshire. The range, introduced five years ago, was revamped last year and extended to 200 lines.

The Co-op is also seeking to make further inroads into the barbecue market with new products in its Summer Eating range, including vegetarian and salad lines. "The barbecue season is very important to The Co-operative, and our Truly Irresistible sausages and burgers are our bestselling summer lines," said Lynne Forbes, category development
