Glares from extremely sarcastic members of parliament (6)
I believe the answer is:
scowls
'glares' is the definition.
(I've seen this in another clue)
'extremely sarcastic members of parliament' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'members of parliament' becomes 'owls' (parliament can mean a group of owls).
'sarcastic' with its centre taken out is 'sc'.
'sc'+'owls'='SCOWLS'
'from' acts as a link.
(Other definitions for scowls that I've seen before include "Wrinkles forehead in disapproval" , "Bad-tempered frowns" , "forbidding looks" , "Gives black looks" , "Furrows forehead in bad humour" .)
