Old Russian cameras put inside centre (8)
I believe the answer is:
rasputin
'old russian' is the definition.
'rasputin' can be an answer for 'russian' (I have seen 'Influential Russian' mean 'rasputin' so perhaps 'russian' could also mean 'rasputin'). I'm unsure of the 'old' bit.
'cameras put inside centre' is the wordplay.
'RASPUTIN' is hidden in amongst the letters.
But, I'm uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for rasputin that I've seen before include "This madman" , "Holy man influential in Russian court" , "sinister Russian" , "Sinister adviser" , "Russian mystic who had influence in tsar's court" .)
