Not gladly received (9)
I believe the answer is:
unwelcome
'not gladly received' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for unwelcome that I've seen before include "Causing displeasure" , "Not gladly received" , "displeasing!" , "No received with pleasure - by host?" , "Bad (news); not acceptable" .)
