Resolute, loyal (7)
I believe the answer is:
staunch
I believe this clue is a double definition.
'resolute' is the first definition.
(I've seen this before)
'loyal' is the second definition.
(I've seen this in another clue)
(Other definitions for staunch that I've seen before include "Sturdy" , "Plug" , "Loyal; restrict (a flow of blood)" , "Stout" , "Hun acts in firm and loyal way" .)
