Recruit this person, turning up with cunning plan (6)
I believe the answer is:
employ
'recruit' is the definition.
(thesaurus)
'this person turning up with cunning plan' is the wordplay.
'this person' becomes 'me' (the person writing).
'turning up' says the letters should be written in reverse.
'with' says to put letters next to each other.
'cunning plan' becomes 'ploy' (I've seen this in another clue).
'me' reversed gives 'em'.
'em'+'ploy'='EMPLOY'
(Other definitions for employ that I've seen before include "Put on the payroll" , "occupation" , "Utilise" , "Give paid work to" , "Give work to (person)" .)
