Drunk leading group of climbers where falling is always likely? (9)
I believe the answer is:
tightrope
'where falling is always likely?' is the definition.
(narrow rope for circus performances)
'drunk leading group of climbers' is the wordplay.
'drunk' becomes 'tight' (I've seen this before).
'leading' is a charade indicator (letters next to each other).
'group of climbers' becomes 'rope' (group of climbers connected by a rope).
'tight'+'rope'='TIGHTROPE'
(Other definitions for tightrope that I've seen before include "Acrobat's walkway" , "High wire" , "Balancing act wire" , "On which acrobats walk" , "Entertaining line" .)
