Pot, joint along with alcoholic drink for pompous official (10)
I believe the answer is:
panjandrum
'pompous official' is the definition.
(I've seen this before)
'pot joint along with alcoholic drink' is the wordplay.
'pot' becomes 'pan' (I've seen this before).
'joint along' becomes 'j' (I can't explain this - if you can you should give a lot more credence to this answer).
'with' becomes 'and'.
'alcoholic drink' becomes 'rum' (alcoholic spirit).
'pan'+'j'+'and'+'rum'='PANJANDRUM'
'for' is the link.
Can you help me to learn more?
(Other definitions for panjandrum that I've seen before include "man of great influence" , "pompous official" , "Person in high authority" , "influential man" , "Big cheese" .)
