From Sainsbury's website:
<<Customer Information: Due to the current conflict in Ukraine, it may be necessary to substitute sunflower oil for other oils in some products. Rapeseed oil is the most likely replacement, but other oils may be used. Customer safety is very important to us, and we have taken care to ensure that there is no allergen risk from any of the substituted oils.>>
I think this back to front. I presume there is a shortage of Ukrainian sunflower oil, in which case they might need to substitute rapeseed for sunflower oil.
Is this just me?
