Take no comfort in organised riot — ugh! (5,2)
I believe the answer is:
rough it
'take no comfort' is the definition.
(I've seen this before)
'in organised riot ugh' is the wordplay.
'in' is an insertion indicator.
'organised' is an anagram indicator.
'riot' anagrammed gives 'roit'.
'roit' placed around 'ugh' is 'ROUGH IT'.
(Other definitions for rough it that I've seen before include "take no comfort" , "Exist with only the basics" , "live without usual comforts" , "Backpack" , "Live in discomfort" .)
