Long and complicated procedure (9)

I believe the answer is:

rigmarole

'long and complicated procedure' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for rigmarole that I've seen before include "Long, complex stuff" , "Long, complicated and confusing procedure" , "Complex procedure" , "Nonsensical procedure" , "Rambling account" .)

I've seen this clue in The Guardian.
