Awkward and lumbering in an ugly manoeuvre? (8)
I believe the answer is:
ungainly
'awkward and lumbering' is the definition.
'in an ugly manoeuvre?' is the wordplay.
'manoeuvre?' is an anagram indicator (I've seen 'manoeuvre' mean this).
'in'+'an'+'ugly'='inanugly'
'inanugly' is an anagram of 'UNGAINLY'.
(Other definitions for ungainly that I've seen before include "Clumsly, maladroit" , "Clumsy or awkward, as nun gaily goes about" , "Lacking grace in movement" , "Physically clumsy or maladroit" , "Clumsy, not coordinated" .)
