Response from Walkers direct 

Hi, Thank you for getting in touch.
I would like to apologise for any confusion caused by the recent message you have seen regarding Walkers Max Paprika flavour crisps.
I can confirm that, as stated on the back of packs, Walkers Max Paprika flavour is suitable for a vegetarian diet. I would, however, like to make you aware that our new Walkers Stax Paprika flavour are not suitable for a vegetarian diet.
I hope this helps, please feel free to call our team on 0800 274777 if you have any further questions at all. Have a lovely day!
