VIP from Lancashire, perhaps, on jumbo (3,6)
I believe the answer is:
big cheese
'vip' is the definition.
(I've seen this before)
'lancashire perhaps on jumbo' is the wordplay.
'lancashire perhaps' becomes 'cheese'.
'on' means one lot of letters go next to another.
'jumbo' becomes 'big' ('big' can be similar in meaning to 'jumbo').
'cheese' after 'big' is 'BIG CHEESE'.
'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" .)
