Germany have the side? Absolutely! (9)
I believe the answer is:
downright
'absolutely' is the definition.
(thesaurus)
'germany have the side?' is the wordplay.
'germany' becomes 'd' (international vehicle registration code).
'have' becomes 'own' ('own' can be a synonym of 'have').
'the side?' becomes 'right'.
'd'+'own'+'right'='DOWNRIGHT'
(Other definitions for downright that I've seen before include "Frank" , "Plain-spoken" , "blunt" , "True" , "Utter, complete" .)
