Nestle is recalling some of its Kit Kat chocolate range after small pieces of plastic were found in some of the products.

The recall affects the Kit Kat Chunky Collection Giant Egg, the Kit Kat Chunky Hazelnut multipack and four Kit Kat Chunky special variety bars including peanut butter, hazelnut, choc fudge and caramel flavours.

All of the affected products have best before dates in 2013 and 2014.

Nestle says any consumers who have purchased them should not eat them and return them unopened to the company for a full refund.
