Shock from Conservative in chosen path (11)
I believe the answer is:
electrocute
'shock' is the definition.
(give an electric shock)
'conservative in chosen path' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'in' is an insertion indicator.
'chosen' becomes 'elect' ('elect' as an adjective can mean chosen).
'path' becomes 'route' (synonyms).
'elect'+'route'='electroute'
'c' going within 'electroute' is 'ELECTROCUTE'.
'from' acts as a link.
(Other definitions for electrocute that I've seen before include "finish with power" , "Shock greatly!" , "Kill, injure by a shock" , "end with a shock?" , "overcharge?" .)
