Uninvited and unwelcome visitor (8)

Ross

I believe the answer is:

intruder

'uninvited and unwelcome visitor' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for intruder that I've seen before include "Burglar, or one who barges in" , "Uninvited person like burglar" , "Illegal entrant" , "Unwelcome guest" , "Trespasser" .)

I've seen this clue in The Guardian.
