Self-help group rank badly in Eurasian capital? (6)
I believe the answer is:
ankara
'eurasian capital?' is the definition.
(I've seen this in another clue)
'self-help group rank badly in' is the wordplay.
'self-help group' becomes 'aa' (Alcoholics Anonymous).
'badly' is an anagram indicator.
'in' means one lot of letters goes inside another.
'rank' is an anagram of 'nkar'.
'aa' placed around 'nkar' is 'ANKARA'.
(Other definitions for ankara that I've seen before include "European capital" , "Capital established by Ataturk" , "Capital of 8 across" , "Capital of Turkey" , "Capital city" .)
