Singer led drunkenly into A&E (5)
I believe the answer is:
adele
'singer' is the definition.
(I've seen this before)
'led drunkenly into ae' is the wordplay.
'drunkenly' indicates anagramming the letters.
'into' indicates putting letters inside.
'led' with letters rearranged gives 'del'.
'del' inserted inside 'ae' is 'ADELE'.
(Other definitions for adele that I've seen before include "Woman" , "girl" , "Performer" , "Singer with albums titled 19, 21 and 25" , "Popular female singer" .)
