Kellogg plans to roll out additions to its Special K, Crunchy Nut and Pringles ranges in the UK in January.

The company is launching a Special K product on sale across the English Channel in France, taking Crunchy Nut into a new category and adding a flavour to its Pringles portfolio.

Kellogg will roll out Special K Chocolate to provide more variety for those looking to lose weight, it said.

Ruth Gresty, Special K brand manager, said the line would "fill a real gap in the market". She said: "It offers women something which they want - chocolate - but at the same time they don't have to worry about breaking the calorie bank so it is a great sales opportunity."

The US cereal giant also plans to take Crunchy Nut into the granola category to tap into a growing segment of the sector in the UK. It will launch Crunchy Nut Glorious Oat Granola in two flavours - fruit and nut, as well as chocolate and hazelnut.

"Muesli and hot [cereal] are the fastest growing areas of the category and are areas in which we don't play," Stephen McDermott, trade sector controller at Kellogg, said.

The launch of chicken-flavoured Pringles will be the first SKU developed since Kellogg acquired the snacks brand in June.

Fiachra Maloney, Pringles brand manager, said the new line was a "big opportunity" for Pringles in a sub-segment in which there was "only really one brand in the market".
