Obstruct basket (6)
I believe the answer is:
hamper
I believe this clue is a double definition.
'obstruct' is the first definition.
(thesaurus)
'basket' is the second definition.
(hamper is a kind of basket)
(Other definitions for hamper that I've seen before include "Food parcel" , "Food box; impede" , "Picnic box" , "Obstruct or delay with food basket" , "Food-basket" .)
