Regales again and withdraws (8)
I believe the answer is:
retreats
I believe this is a double definition.
'regales again' is the first definition.
('treats' can be a synonym for 'regales' so perhaps 'retreats' is OK for 'regales again')
'withdraws' is the second definition.
(I know this)
'and' acts as a link.
(Other definitions for retreats that I've seen before include "Backs away" , "Refuges" , "tactical withdrawals" , "Places that afford peace and quiet" , "Recedes" .)
