I'd like to propose one that only angers & upsets tory euro-sceptics, extreme irish republicans and the right wing generally.

The Northwestern European Isles (NEI) we could even add Iceland and Fero Islands [Linked Image]

As it stands:

British Isles - Geographic Identity

anything else is a political / national identity.

Spain has a similar situation to the UK with various national identities all stuck together under one banner "Spain".

(Republic of Ireland excluded from that comparision)
