Country accommodating society sycophants (3,3)
I believe the answer is:
yes men
'sycophants' is the definition.
(I've seen this before)
'country accommodating society' is the wordplay.
'country' becomes 'yemen' (Yemen is an example).
'accommodating' means one lot of letters goes inside another.
'society' becomes 's' (common abbreviation in names of organisations).
'yemen' enclosing 's' is 'YES-MEN'.
(Other definitions for yes men that I've seen before include "Unquestioning conformists" , "Sycophants like assenting males" , "Willing conformers" , "Unquestioning followers" , "They agree to everything" .)
