Get chairs out for assembly in Germany (9)
I believe the answer is:
reichstag
'assembly in germany' is the definition.
(parliament building)
'get chairs out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'get'+'chairs'='getchairs'
'getchairs' with letters rearranged gives 'REICHSTAG'.
'for' acts as a link.
(Other definitions for reichstag that I've seen before include "Berlin building burnt in 1933" , "German parliament building" , "Continental diet" , "Foreigners assembled" , "Former German parliament" .)
