Asking one to tell it all over again (9,1,7)
I believe the answer is:
demanding a recount
'again' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'asking one to tell it all over' is the wordplay.
I cannot really understand how this works, but
'asking' could be 'demanding' ('demand' can be a synonym of 'ask') and 'demanding' is present in the answer.
'one' could be 'un' (I've seen this in other clues) and 'un' is found within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
'over' could be 're' and 're' is located in the answer.
This explanation may well be incorrect...
