A predominatly Dutch company moving its "Legal" dept from UK back to cloggiland... So lots of racist Brexit disaster depair from the usual suspects and fellow travellers.
Also, it's an FTSE100 PLC - owned by
shareholders not Britain, Holland or EU.
Circa 45% of shareholders are Dutch investors (corporate & individuals).
Circa 60% of Unilever's profits come from UK based business sectors.
Main reason for move is Protectionism - Dutch Gov't much more likely to back incumbent Mgt and prevent owners (shareholders) selling to a buyer who will pay a higher price than current market price.

Make it personal:
Your car has a UK market value of £10,000
American on holiday says "Nice car dude, I will buy it for £12,500 cash"
You're happy, American guy happy. Then Gov't says NO.
It's your car
not Gov't's car.
