The Summer Olympics are coming up, so I thought now would be a good time to provide a primer on England and the United Kingdom:
England and U.K. are the same – but only in the way that Texas and the U.S. are the same. One is contained within the other.
According to the AP Stylebook, the United Kingdom “consists of Great Britain and Northern Ireland.” Great Britain (aka Britain) “consists of England, Scotland and Wales.” Note that the Irish Republic is not part of the U.K.
It’s acceptable to use U.K. in all instances. In headlines, however, you don’t need the periods.
The only dateline city in England (and all of the U.K.) is London. Everything else needs the country with it. For example, it would be Manchester, England.
