That is one of the most tenuous links I have ever seen -so tenuous in fact, as to be non-existent.
If you want to create a debate about why Norway declines to join the Euro, thats fine, but using this story as some sort of relevant link is just absurd. How about finding a story that actually illustrates the questions over benefits or otherwise of EU membership?
And, for the record - Are you attempting to claim that the reason that the UK does not have a sovereign wealth fund is somehow connected to our membership of the EU?
