Conservative getting in money counter (4)
I believe the answer is:
chip
'money counter' is the definition.
'conservative getting in' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'getting' says to put letters next to each other.
'in' becomes 'hip' (both can mean fashionable).
'c'+'hip'='CHIP'
(Other definitions for chip that I've seen before include "Gaming counter" , "Small fragment of wood" , "Maybe silicon or potato" , "Bit of potato - golf shot" , "Thin piece, of wood or potato say" .)
