Man with a van (5)
I believe the answer is:
mover
'man with a van' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mover that I've seen before include "Dynamic type" , "Someone who proposes a motion for debate" , "someone who brings forward proposal" , "One who is in motion - may also be a shaker" , "Instigator, organiser" .)
