Right plugs he noted going wrong? Remove from power (8)
I believe the answer is:
dethrone
'remove from power' is the definition.
(I've seen this in another clue)
'right plugs he noted going wrong?' is the wordplay.
'right' becomes 'r' (abbreviation).
'plugs' means one lot of letters goes inside another (plug can mean to fill a gap).
'going wrong?' indicates an anagram.
'he'+'noted'='henoted'
'henoted' is an anagram of 'dethone'.
'r' going into 'dethone' is 'DETHRONE'.
(Other definitions for dethrone that I've seen before include "Remove from seat" , "Topple" , "Remove from position" , "Remove (king)" , "Unseat" .)
