Problem: British Isles:

Reciprocal arrangements allow British and Irish citizens to full voting rights in the two states. Exceptions to this are presidential elections and constitutional referendums in the Republic of Ireland, for which there is no comparable franchise in the other states. In the United Kingdom, these pre-date European Union law, and in both jurisdictions go further than that required by European Union law. Other EU nationals may only vote in local and European Parliament elections while resident in either the UK or Ireland. In 2008, a UK Ministry of Justice report investigating how to strengthen the British sense of citizenship proposed to end this arrangement arguing that, "the right to vote is one of the hallmarks of the political status of citizens; it is not a means of expressing closeness between countries."

Which entity supports that the right to vote is a hallmark of economic status?

A:
unanswerable
