Talk about minister's latest plan (5)
I believe the answer is:
chart
'plan' is the definition.
(I've seen this before)
'talk about minister's latest' is the wordplay.
'talk' becomes 'chat' (I've seen this before**).
'about' indicates putting letters inside.
'latest' indicates one should take the final letters.
The last letter of 'minister' is 'r'.
'chat' placed around 'r' is 'CHART'.
(Other definitions for chart that I've seen before include "Marine map" , "[LOVE ME DO] became the first of many to ..." , "Hit parade" , "Visual display of information" , "what could be a pie" .)
