Member of Parliament, following magnificent sporting event since 1967 (9)
I believe the answer is:
superbowl
'sporting event since 1967' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'member of parliament following magnificent' is the wordplay.
'member of parliament' becomes 'owl' ('parliament' is the collective noun for 'owl').
'following' is a charade indicator (letters next to each other).
'magnificent' becomes 'superb' (I've seen this before).
'owl' after 'superb' is 'SUPERBOWL'.
Can you help me to learn more?
(Other definitions for superbowl that I've seen before include "sporting event" , "American competition?" , "big game in America" .)
