The thing that large corporations should remember is the the UK is one of the few countries in the world that can pass retrospective legislation and then enforce it (this has happened on tax issues as recently as the 2000s). At some stage a UK government is going to claw back this money and I think it won't be pretty for anyone. (NB I fundamentally don't agree with the concept of retrospective legislation I'm merely saying the UK can do it.)
