Domicile is not just a domestic issue: I was interviewed on the issue in La Tribune in France yesterday. You can see the article here. Readers of this blog will note where they got the picture from.
There's an important point in the article: I suggest that the domicile rule is and will remain after 6 April unjustifiable subsidy to the UK's financial services industry that can be challenged under Europe's state aid rules. I do hope the French pick this up.
