Conservative and liberal creep in embrace (6)
I believe the answer is:
clinch
'embrace' is the definition.
(I know that clinch is a type of embrace)
'conservative and liberal creep' is the wordplay.
'conservative' becomes 'C' (UK political abbreviation).
'and' says to put letters next to each other.
'liberal' becomes 'l' (abbreviation).
'creep' becomes 'inch' (I've seen this before).
'c'+'l'+'inch'='CLINCH'
'in' is the link.
(Other definitions for clinch that I've seen before include "seal" , "Grapple - confirm" , "Drive home (an argument)" , "Matthew ---; --- Schoenberg" , "Passionate embrace" .)
