One's inclined to associate politician with troops (4)
I believe the answer is:
ramp
'one's inclined' is the definition.
(I've seen this before)
'associate politician with troops' is the wordplay.
'associate politician' becomes 'mp' (I am not sure about the 'associate' bit.**).
'with' is a charade indicator (letters next to each other).
'troops' becomes 'ra' (Royal Artillery).
'mp' after 'ra' is 'RAMP'.
'to' is the link.
(Other definitions for ramp that I've seen before include "One's inclined" , "Sloping surface connecting two levels" , "motorway access road" , "aircraft steps?" , "Sloping platform" .)
