Pull dustcart taking back bottles (7)
I believe the answer is:
attract
'pull' is the definition.
(I know that pull can be written as attract)
'dustcart taking back bottles' is the wordplay.
'bottles' indicates the answer is hidden within the clue (bottling is a kind of containing).
'back' is a reversal indicator.
'tcartta' is hidden within 'dustcart taking'.
'tcartta' in reverse letter order is 'ATTRACT'.
(Other definitions for attract that I've seen before include "Draw towards or get attention of" , "Draw towards, being magnetic" , "Draw towards one, as magnet does metal" , "Entice" , "'Draw, charm (7)'" .)
