To be blunt it's irrelevant (9)
I believe the answer is:
pointless
This clue is a double definition.
'to be blunt' is the first definition.
(similar in meaning)
'irrelevant' is the second definition.
(I've seen this before)
'it's' is the link.
(Other definitions for pointless that I've seen before include "Without purpose" , "Having little use" , "Having no bits of news" , "Serving no purpose" , "like a team that always loses?" .)
