Outgoing leader rings daughter as instructed (6)
I believe the answer is:
bidden
'instructed' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'outgoing leader rings daughter' is the wordplay.
'outgoing leader' becomes 'biden' (I can't justify this - if you can you should give a lot more credence to this answer).
'rings' indicates putting letters inside (some letters are ringed or contained by others).
'daughter' becomes 'd' (genealogical abbreviation).
'biden' going around 'd' is 'BIDDEN'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for bidden that I've seen before include "Asked" , "Commanded (to do something)" , "Ordered (to)" .)
