Let’s take the Ode of Tonyness
It seems that children in England are to be taught ‘Britishness’ in school. Aside from the fact that political indoctrination of any kind has no place in the classroom, there simply is no such thing as Britishness. There is Scottishness, Englishness and Welshness (whether or not we should include Northern Ireland in the term ‘Britishness’, since it is on a separate island, is not something I have time to discuss here).
The idea that there is a single ‘British’ national identity just because we have a British government is as ludicrous as the suggestions that we have a ‘European’ national identity just because we have the European Union. The fact that different countries share a government does not mean that they share a national identity.
