Meat traveller brought back in covered basket (6)
I believe the answer is:
hamper
'covered basket' is the definition.
(as in a picnic hamper)
'meat traveller brought back' is the wordplay.
'meat' becomes 'ham' (ham is a kind of meat).
'traveller' becomes 'rep' (travel company worker).
'brought back' says the letters should be written backwards.
'rep' reversed gives 'per'.
'ham'+'per'='HAMPER'
'in' is the link.
(Other definitions for hamper that I've seen before include "Christmas basket" , "Food-basket" , "basket with a cover" , "Hinder; basket" , "Impede the movement" .)
