Run out in big limo abroad causes complicated situation (9)
I believe the answer is:
imbroglio
'complicated situation' is the definition.
(I've seen this before)
'run out in big limo abroad' is the wordplay.
'run out' becomes 'ro' (cricket abbreviation).
'in' is an insertion indicator.
'abroad' is an anagram indicator.
'big'+'limo'='biglimo'
'biglimo' anagrammed gives 'imbglio'.
'ro' placed inside 'imbglio' is 'IMBROGLIO'.
'causes' is the link.
(Other definitions for imbroglio that I've seen before include "Jumble" , "Confused and tangled situation" , "quandary" , "Confused mess" , "Dilemma" .)
