MPs’ business finishing early is prudent (7)
I believe the answer is:
politic
'is prudent' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for politic that I've seen before include "Prudent, discreet" , "Prudent and tactful" , "Advisable" , "artful" , "Expedient" .)
