Censured about plot involving UK (7)
I believe the answer is:
rebuked
'censured' is the definition.
(I've seen this in another clue)
'about plot involving uk' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'plot' becomes 'bed' (a plot of land).
'involving' is an insertion indicator.
'bed' placed around 'uk' is 'buked'.
're'+'buked'='REBUKED'
(Other definitions for rebuked that I've seen before include "Remonstrated" , "Scolded" , "Upbraided" , "Sharply reprimanded" , "Berated, censured" .)
