Official shoots rook, maybe following order (9)
I believe the answer is:
ombudsman
'official' is the definition.
(I've seen this before)
'shoots rook maybe following order' is the wordplay.
'shoots' becomes 'buds'.
'rook maybe' becomes 'man' (I can't justify this - if you can you should believe this answer much more).
'following' means one lot of letters go next to another.
'order' becomes 'om' (Order of Merit).
'buds'+'man'='budsman'
'budsman' put after 'om' is 'OMBUDSMAN'.
Can you help me to learn more?
(Other definitions for ombudsman that I've seen before include "Parliamentary commissioner" , "Complaint investigator" , "Official pursuing complaints against government departments" , "Official investigating complaints of maladministration" , "one appointed to investigate complaints" .)
