Drunk in club ultimately having runs? (9)
I believe the answer is:
bladdered
'drunk' is the definition.
(I know that drunk can be written as bladdered)
'club ultimately having runs?' is the wordplay.
'ultimately' suggests the final letters.
'having runs?' becomes 'laddered' (run or ladder can mean a tear in tights).
The final letter of 'club' is 'b'.
'b'+'laddered'='BLADDERED'
'in' is the link.
(Other definitions for bladdered that I've seen before include "Well away" , "Drunk (slang)" .)
