Mixer — there’s litres used in drunken spree (7)
I believe the answer is:
'mixer' is the definition.
(I've seen this before)
'litres used in drunken spree' is the wordplay.
'litres' becomes 'l'.
'used in' is an insertion indicator.
'drunken spree' becomes 'bender' (I've seen this before).
'l' put within 'bender' is 'BLENDER'.
'there's' is the link.
(Other definitions for blender that I've seen before include "kitchen equipment" , "(Food) mixer" , "used to make assets liquid?" , "Kitchen utensil" , "Kitchen machine" .)
