Turkish capital in the bank a raffle provides (6)
I believe the answer is:
ankara
'turkish capital' is the definition.
(capital of Turkey)
'bank a raffle provides' is the wordplay.
'provides' indicates the answer is hidden within the clue.
'ANKARA' is hidden within 'bank a raffle'.
'in the' acts as a link.
(Other definitions for ankara that I've seen before include "Turkish city" , "Capital of Turkey" , "Turkish capital" , "Capital established by Ataturk" , "Turkey's capital" .)
