Attend a party uninvited (9)

I believe the answer is:

gatecrash

(Other definitions for gatecrash that I've seen before include "join party unofficially" , "enter without invitation" , "Try to get in for free" , "to do so uninvited" , "join party if not wanted" .)

I've seen this clue in the Sydney Morning Herald.
