Nanny runs out in front of media, panicking (9)
I believe the answer is:
nursemaid
'nanny' is the definition.
('nursemaid' can be a synonym of 'nanny')
'runs out in front of media panicking' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'in front of' means one lot of letters go next to another.
'panicking' indicates anagramming the letters.
'runs' anagrammed gives 'nurs'.
'media' is an anagram of 'emaid'.
'nurs'+'emaid'='NURSEMAID'
(Other definitions for nursemaid that I've seen before include "Childminder" , "employ one for small charge" , "Be overprotective towards (someone)" , "tender" , "Alice, for example" .)
