Corsica gendarme clutching to-do list (6)
I believe the answer is:
agenda
'to-do list' is the definition.
(to-do list for a meeting)
'corsica gendarme clutching' is the wordplay.
'clutching' says the answer is hidden in the clue.
'AGENDA' is hidden within 'corsica gendarme'.
(Other definitions for agenda that I've seen before include "Matters to be addressed" , "List of matters to be discussed at a meeting" , "Topic list for meeting" , "List of items to be dealt with" , "Schedule of items for meeting" .)
