accede

I'm a little stuck... Click here to teach me more about this clue!

'assent' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for accede that I've seen before include "Agree to proposal or take office" , "Grant, agree to proposal" , "Assent (to something)" , "Agree or enter into office" , "Agree (to) - come into office" .)

I've seen this clue in the Evening Standard.
