VIP from Lancashire, perhaps, on jumbo (3,6)
I believe the answer is:
Here is my best explanation:
'vip' is the definition.
(I've seen this before)
'lancashire perhaps on jumbo' is the wordplay.
'lancashire perhaps' becomes 'cheese'.
'on' is a charade indicator (letters next to each other).
'jumbo' becomes 'big' ('big' can be similar in meaning to 'jumbo').
'cheese' put after 'big' is 'bigcheese'.
'from' is the link.
(Other definitions for big cheese that I've seen before include "Important person (slang)", "Large cake of Cheshire, perhaps", "Mousetrap attraction!", "Notable", "VIP", "boss" and "Important chap".)
