[poorclare]

Thank you my friends.
I must be wrong somewhere as 08d Asseverate
for 10a Not an undercover operator I have Nudity ?
for 11a Favourable outcome I have whilst running ~ I have Successes
that leave me with ??t?e?r?t?

[JJ109]

Isn't 11a Successive (success + I've) but that is 10 letters and successes = 9 letters. Difficult to follow what you require

[JJ109]

10a Could be Nudist!

[Flonska]

Try 10a = Nudist?

[poorclare]

Thank you Flonska Nudist it is, so Asseverate now fits
Thanks to all for your patience and help.
Hope you have a lovely afternoon/evening.
Finished now
