A Republican administered Scottish island (5)

I believe the answer is:

arran

'scottish island' is the definition.
(I've seen this before)

'a republican administered' is the wordplay.
'republican' becomes 'r' (abbreviation).
'administered' becomes 'ran' (I've seen this before).
'a'+'r'+'ran'='ARRAN'

(Other definitions for arran that I've seen before include "Scottish territory" , "Isle near Firth of Clyde" , "Scottish island" , "Firth of Clyde island" .)

I've seen this clue in The Independent.
