Means of contacting spook needs approval from Paris and Berlin (5)

I believe the answer is:

ouija

'means of contacting spook' is the definition.
(ouija board - spook can mean a ghost)

I cannot understand how the rest of the clue works.

(Other definitions for ouija that I've seen before include "This board is used in spiritualistic sessions" , "Kind of board used in seances" , "Board able to answer questions?" , "Something to raise spirits" , "Board sometimes used at seances" .)

I've seen this clue in The Independent.
