Episode going wrong in end? It encapsulates Conservative (8)
I believe the answer is:
incident
'episode' is the definition.
(I've seen this before)
'going wrong in end? it encapsulates conservative' is the wordplay.
'going wrong' is an anagram indicator.
'encapsulates' is an insertion indicator.
'conservative' becomes 'C' (UK political abbreviation).
'in'+'end'+'it'='inendit'
'inendit' is an anagram of 'inident'.
'inident' placed around 'c' is 'INCIDENT'.
(Other definitions for incident that I've seen before include "Cited inn as source of happening" , "Event found ten in CID mix-up" , "hostile clash" , "Falling" , "Event, occurence" .)
