Slow, scruffy members of parliament? (4)
I believe the answer is:
owls
'members of parliament?' is the definition.
(parliament can mean a group of owls)
'slow scruffy' is the wordplay.
'scruffy' is an anagram indicator (I've seen this in other clues).
'slow' with letters rearranged gives 'OWLS'.
(Other definitions for owls that I've seen before include "Slow sort of birds" , "Strigiform creatures" , "Avian symbols of wisdom" , "Nocturnal hooters?" , "Members of Parliament" .)
