Impede the movement of basket (6)
I believe the answer is:
hamper
I believe this clue is a double definition.
'impede the movement' is the first definition.
(I've seen this before)
'basket' is the second definition.
(eg food hamper)
'of' acts as a link.
(Other definitions for hamper that I've seen before include "Hinder, impede" , "Prevent free movement" , "Large covered basket" , "Christmas basket" , "Food-basket" .)
