Rule on, when carrying the raid out (6)
I believe the answer is:
ordain
'rule' is the definition.
(I've seen this before)
'when carrying the raid out' is the wordplay.
'when' becomes 'on' (I've seen this in other clues).
'carrying' means one lot of letters goes inside another.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'raid' is an anagram of 'rdai'.
'on' going around 'rdai' is 'ORDAIN'.
'on' acts as a link.
(Other definitions for ordain that I've seen before include "Decree authoritatively" , "Confer holy orders upon" , "Appoint as priest" , "Make someone a clergyman" , "Make a decree" .)
