VIP's six at Lord's? (3,4)
I believe the answer is:
big shot
This clue is a double definition.
'vip's' is the first definition.
(both can mean an important person)
'six at lord's?' is the second definition.
(a six would be a big shot in cricket)
(Other definitions for big shot that I've seen before include "Important person (with a large cannon?)" , "Important man with loud gun?" , "Head honcho?" , "Informally, an important person - sounds loud" , "Important influential person" .)
