Reveal ad ill-advisedly featuring former Taoiseach (2,6)
I believe the answer is:
de valera
'reveal ad ill-advisedly featuring former taoiseach' is the definition.
I can't judge whether this definition defines the answer.
'reveal ad ill' is the wordplay.
'ill' indicates anagramming the letters.
'reveal'+'ad'='revealad'
'revealad' with letters rearranged gives 'DE VALERA'.
Can you help me to learn more?
(Other definitions for de valera that I've seen before include "Head of state" , "Eamon -- --, Irish prime minister and president" , "Otherwise known as the 'Long Fella'" , "Dear veal for iconic Irish statesman" , "Old Irish nationalist" .)
