British Member of Parliament for York? (4)
I believe the answer is:
bowl
'york?' is the definition.
(I know that york is a more specific form of bowl)
'british member of parliament' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'member of parliament' becomes 'owl' ('parliament' is the collective noun for 'owl').
'b'+'owl'='BOWL'
'for' is the link.
(Other definitions for bowl that I've seen before include "Wooden ball used in lawn game" , "Basin; attack wicket" , "Round vessel - wooden ball" , "Greatly surprise" , "Play with tenpins" .)
