Least awkward bargain (5)
I believe the answer is:
steal
'bargain' is the definition.
(I know that bargain can be written as steal)
'least awkward' is the wordplay.
'awkward' indicates anagramming the letters.
'least' is an anagram of 'STEAL'.
(Other definitions for steal that I've seen before include "crib" , "Whip" , "Walk off with" , "a snip!" , "pirate" .)
