Acquiesce, defer (6)

I believe the answer is:

accede

This clue is a double definition.

'acquiesce' is the first definition.
(synonyms)

'defer' is the second definition.
(synonyms)

(Other definitions for accede that I've seen before include "Yield" , "Assent, to a demand say" , "Give one's consent" , "Say yes to request" , "Agree or enter into office" .)

I've seen this clue in The Irish Times.
