In manner of a member of parliament? (8)

Ross

I believe the answer is:

owlishly

I'm a little stuck... Click here to teach me more about this clue!

'in manner of a' is the definition.
I can't judge whether this definition defines the answer.

'member of parliament?' is the wordplay.
'member' becomes 'owl' (I have seen 'Member of Parliament' mean 'owl' so perhaps 'member' could also mean 'owl').
'of parliament?' becomes 'ishly' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'owl'+'ishly'='OWLISHLY'

Can you help me to learn more?

(Other definitions for owlishly that I've seen before include "blinking in this fashion?" , "with wise or solemn manner" .)

I've seen this clue in The Everyman puzzle in The Observer.
