Walk with a swagger; supporting rod (5)
I believe the answer is:
strut
I believe this clue is a double definition.
'walk with a swagger' is the first definition.
(I've seen this in another clue)
'supporting rod' is the second definition.
(I've seen this before)
(Other definitions for strut that I've seen before include "Walk in pompous self-satisfied way" , "Walk proudly; brace" , "Supporting bar" , "Prop; prance" , "Walk proudly, swagger" .)
