Is Buddhist priest ill in capital? (9)
I believe the answer is:
islamabad
'capital?' is the definition.
(capital of Pakistan)
'is buddhist priest ill' is the wordplay.
'buddhist priest' becomes 'lama' (as in the Dalai Lama).
'ill' becomes 'bad' (similar in meaning).
'is'+'lama'+'bad'='ISLAMABAD'
'in' acts as a link.
(Other definitions for islamabad that I've seen before include "Capital of Pakistan" , "Pakistan's capital" , "Asian city" , "capital city" , "city of Pakistan?" .)
