Cockney stocking seller and basket maker (5)
I believe the answer is:
osier
I believe this clue is a double definition.
'cockney stocking seller' is the first definition.
('hosier' - I've seen this in another clue - said with a cockney accent, dropping the 'H')
'basket maker' is the second definition.
(I've seen this before)
'and' acts as a link.
(Other definitions for osier that I've seen before include "Basket-maker" , "Wood" , "... source of twigs to make baskets" , "Small willow; its shoot" , "Bit of tree" .)
