This is the entire clue.

(Other definitions for united kingdom that I've seen before include "UK, expanded" , "Where you may well be" , "Great Britain and Northern Ireland" , "Our island nation" , "England, Scotland, Wales and Northern Ireland" .)

I've seen this clue in the Sydney Morning Herald.
