Partly embrace devolution and hand over (4)
I believe the answer is:
cede
'hand over' is the definition.
(I've seen this in another clue)
'partly embrace devolution and' is the wordplay.
'partly' indicates a hidden word (part of the clue is used).
'CEDE' is hidden in the letters of 'embrace devolution and'.
(Other definitions for cede that I've seen before include "Give up rights or possession" , "Deliver" , "Reluctantly give up" , "Yield, give way" , "Relinquish control of" .)
