Consequences of that farmer virtually being drunk (9)
I believe the answer is:
aftermath
'consequences' is the definition.
(the aftermath of something is its consequences)
'that farmer virtually being drunk' is the wordplay.
'virtually' means to remove the last letter (all but the last letter).
'being drunk' indicates an anagram.
'that'+'farmer'='thatfarmer'
'thatfarmer' with its final letter taken off is 'thatfarme'.
'thatfarme' anagrammed gives 'AFTERMATH'.
'of' is the link.
(Other definitions for aftermath that I've seen before include "Sequel" , "Second possible harvest" , "Consequential circumstances" , "Outcome of being at the farm" , "Subsequent circumstances" .)
