Premier attends party in government - embarrassing! (8)
I believe the answer is:
abashing
'embarrassing' is the definition.
('abash' can be a synonym of 'embarrass')
'premier attends party in government' is the wordplay.
I cannot really see how this works, but
'party' could be 'bash' (term for a party or celebration) and 'bash' is found in the answer.
'in' is present in the answer.
'government' could be 'g' (abbreviation for government) and 'g' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for abashing that I've seen before include "embarrassing" , "disconcerting" , "humiliating" , "Causing to feel self-conscious" .)
