A bit reminiscent, possibly, of senior politician (7,8)
I believe the answer is:
cabinet minister
'senior politician' is the definition.
(I've seen this before)
'a bit reminiscent possibly' is the wordplay.
'possibly' is an anagram indicator.
'a'+'bit'+'reminiscent'='abitreminiscent'
'abitreminiscent' anagrammed gives 'CABINET MINISTER'.
'of' acts as a link.
(Other definitions for cabinet minister that I've seen before include "went down to provide 22 24 [WHISKY GALORE] - with 17d" , "May perhaps" , "high-ranking member?" , "senior politician" , "member of government" .)
