Apologies guest, Allan and all: serious mistake on my part. For some reason I can't explain, I thought Uruguay's population was larger and Glasgow's smaller than they respectively are. The Glasgow population was Britain's second largest in my infancy (but not as big as Uruguay's). I see now that it has dwindled to half its former size thanks to boundary changes, resettlement to surrounding tow,ns etc.

Uruguay is still the smallest country in the tournament, by population.
