Hold up basket (6)
I believe the answer is:
hamper
I believe this is a double definition.
'hold up' is the first definition.
(I've seen this before)
'basket' is the second definition.
(hamper is a kind of basket)
(Other definitions for hamper that I've seen before include "Food parcel" , "big basket" , "Hinder, impede" , "Impede with picnic basket?" , "Slow up - basket" .)
