Devoid of diplomacy (8)

Ross

I believe the answer is:

tactless

(Other definitions for tactless that I've seen before include "Without subtlety or sensitivity" , "Gaffe-prone" , "Lacking sensitivity in dealing with others" , "Lacking diplomacy" , "Showing lack of skill in handling delicate situations" .)

I've seen this clue in The Guardian.
