Expects to have to sit around with nawab at centre (6)
I believe the answer is:
awaits
'expects' is the definition.
('await' can be a synonym of 'expect')
'to sit around with nawab at centre' is the wordplay.
'around with' indicates an anagram.
'at centre' means to look at the middle letters.
The middle of 'nawab' is 'awa'.
'sit' with its letters anagrammed with 'awa' gives 'AWAITS'.
'to have' is the link.
(Other definitions for awaits that I've seen before include "Looks forward to" , "Looks for; is in store for" , "Expects" , "Doesn't go" .)
