True Blue Conservative Nationalist creates turmoil (10)
I believe the answer is:
turbulence
'turmoil' is the definition.
(thesaurus)
'true blue conservative nationalist creates' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'nationalist' becomes 'n' (abbreviation in politics).
'creates' is an anagram indicator.
'true'+'blue'+'c'+'n'='truebluecn'
'truebluecn' is an anagram of 'TURBULENCE'.
(Other definitions for turbulence that I've seen before include "Irregularity in flows" , "Disorder in flow" , "that Henry II thought Becket caused?" , "Disorderly or confused state" , "Disturbed state" .)
