Marks & Spencer has recalled a batch of its own-label Sweet and Sour Chicken meal due to a labelling error.

Some packs may contain crispy prawns but this is not displayed on the label, making the product unsafe for people with seafood allergies.

The affected product is M&S Sweet and Sour Chicken 300g, with a use by date of 13 February and a unique product code of 0133470.
