A law student from King's College London, has written a letter to Nestle quoting case law from the 1930s after biting into a waferless Kit Kat. Saima Ahmad, 20, had purchased a multipack of eight Kit Kats for £2 ($2.88) when she stumbled upon a waferless interior, much to her disappointment.

"They go about advertising the unique concept of Kit Kat, but I'm so disappointed by what I have purchased. Clearly, if I wanted to purchase a confectionery item that is purely chocolate, I would have purchased a bar of Galaxy," said Ahmad. "I wouldn't rule out taking this further if Nestle do not apologise or compensate me adequately."

Ahmad is now demanding the manufacturer fully compensate her with a lifetime supply of Kit Kats after her "monetary and emotional" loss, or else face further legal action. According to ITV News, an excerpt from Ahmad's letter to the manufacturer read: "The truth of the matter is; manufacturers owe a duty of care to consumers.

"The specific duty you owe in consistency in your manufacturing process. The failure to take due care in the manufacturing process resulted in a product being defective. As a result I feel as though I have been misled to part with my money and purchase a product that is clearly different from what has been marketed by Nestle. The loss I have suffered is of monetary and emotional significance."

Meanwhile, in other Kit Kat news, Nestle Japan has announced an interesting choice of flavour for the new Kit Kat: sake. The packaging will reportedly be covered in pink cherry blossoms. The sake Kit Kat will reportedly taste like high-end sake and contain white chocolate flavoured bars sprinkled with powdered rice wine.

Sake Kit Kat went on shelves on 1 February and a bite of the juicy bars will reportedly leave a "light and refreshing aftertaste", though it is claimed the bars will be non-alcoholic. Earlier, Nestle launched a gold-wrapped Kit Kat for the Japanese consumers. The "gold" bars were to be priced at ¥2,016 (£11.17, $16, €15.23,) according to Nestle. "When you present a Kit Kat wrapped with gold, you're actually making the very best wish for the person through the year," said Alex Villa, Nestle Japan's executive manager.
