Basket provided by girl in public relations (7)
I believe the answer is:
pannier
'basket' is the definition.
(pannier is a kind of basket)
'girl in public relations' is the wordplay.
'girl' becomes 'annie' ().
'in' is an insertion indicator.
'public relations' becomes 'PR' (abbreviation).
'annie' inserted into 'pr' is 'PANNIER'.
'provided by' acts as a link.
(Other definitions for pannier that I've seen before include "This will carry" , "Basket on, eg, donkey" , "Bike bag" , "Basket carried by beast of burden" , "One of a pair of baskets" .)
