Coca-Cola is recalling some of its Zero Sugar multipacks because of health risks, as some actually contain full-sugar Coke.
The packaging error is a concern to people who need to control their sugar intake, such as diabetics, according to the Food Standards Agency (FSA).
The affected packs have 24 cans of 330ml Coke, with Christmas cardboard packaging.
The problem multipacks have best-before dates of October 31 and November 30, 2023.
Coca-Cola said: "The safety and qualit y of our products is of paramount importance. We are sorry tlhat on this occasion a small number of our products have not met ourrequired standards."
The FSA said: "If you have bought the above product and need to manage your sugar intake, please do not drink it. Instead, contact Coca-Cola on 0800 22 77 11 and they will arrange for you to receive a replacement product."
Coca-Cola Zero Sugar was first brought in during 2005, then had a new version introduced in 2017.
Zero Sugar Coke and Diet Coke are made from the same sweeteners but use a different blend of flavours.
Coca-Cola Zero has been designed to taste more like the original Coca‑Cola, while Diet Coke has a lighter taste.
To achieve these different tastes, Zero Sugar uses sodium citrate and Diet Coke has citric acid.
Earlier this year Coca-Cola started rolling out new cap s on its bottles across Britain.
The caps are connected to 1.5L and 500ml bottles - and they don't pop off when you open the drink.
The change can also be spotted on Fanta, Sprite and Dr Pepper bottles.
The change is an attempt by the company to ensure all parts of their recyclable bottles end up in the recycling bin.
It's an attempt to make it easier for people to ditch their drinks once they're finished - but Coke drinkers on Twitter aren't persuaded.
One wrote: "Not gonna lie. That new attached cap design is annoying."
Coca-Cola began rolling out the cap change in May, and thinks the switch will be completed on all plastic bottles by early 2024.
Jon Woods, general manager at Coca‑Cola Great Britain, said: “This is a small change that we hope will have a big impact, ensuring that when consumers recycle our bottles, no cap gets left behind."
The supermarket brand Lidl has also announced it will be altering packaging to be more environmentally aware.
The budget brand is getting rid of the current packaging on milk tops in exchange for clear plastic lids, which can be recycled more easily.
The upmarket Waitrose also got rid of its red, blue and green milk caps over the summer.
