Walk backwards? Skill for politician (5)
I believe the answer is:
tramp
'walk' is the definition.
(tramp is a kind of walk)
'backwards? skill for politician' is the wordplay.
'backwards?' shows that the letters should be reversed in order (I've seen 'backwards' mean this).
'skill' becomes 'art' (I've seen this before).
'for' means one lot of letters go next to another.
'politician' becomes 'mp'.
'art' reversed gives 'tra'.
'tra'+'mp'='TRAMP'
(Other definitions for tramp that I've seen before include "man down on his luck" , "Vagrant, drifter" , "Trudge; vagrant" , "Down-and-out" , "I usually walk" .)
