New ideas for the assistants (5)
I believe the answer is:
aides
'assistants' is the definition.
(aide is a kind of assistant)
'new ideas' is the wordplay.
'new' is an anagram indicator.
'ideas' is an anagram of 'AIDES'.
'for the' acts as a link.
(Other definitions for aides that I've seen before include "Military assistants to a senior officers" , "They help" , "Ministerial assistants" , "Helpers" , "Adjutants" .)
