Moved aside, chased by son (7)
I believe the answer is:
shunted
'moved aside' is the definition.
(I've seen this before)
'chased by son' is the wordplay.
'chased' becomes 'hunted' (hunting is a kind of chasing).
'by' is a charade indicator (letters next to each other).
'son' becomes 's'.
'hunted' after 's' is 'SHUNTED'.
(Other definitions for shunted that I've seen before include "Moved to one side" , "Moved aside" .)
