Over there in the Yukon, Britain excluded (3)

I believe the answer is:

yon

'over there' is the definition.
(archaic word meaning 'over there')

'yukon britain excluded' is the wordplay.
'britain' becomes 'UK' (synonyms).
'excluded' indicates named letters should be taken away.
'yukon' with 'uk' taken out is 'YON'.

'in the' acts as a link.

(Another definition for yon that I've seen is " Those Scots".)

I've seen this clue in the Evening Standard.
