Former model in show (6)
I believe the answer is:
expose
'show' is the definition.
(I know that expose is a type of bring out)
'former model' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'model' becomes 'pose' (model can mean to pose).
'ex'+'pose'='EXPOSE'
'in' is the link.
(Other definitions for expose that I've seen before include "Show up" , "display" , "outing" , "article on scandal?" , "Unmask or denounce" .)
