Board has go-ahead from Macron and Merkel (5)
I believe the answer is:
ouija
'board' is the definition.
(Ouija board is an example)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for ouija that I've seen before include "This board is used in spiritualism" , "Medium's medium?" , "Board sometimes used at seances" , "(Seance) lettered board" , "This board is used in spiritualistic sessions" .)
