Found this quite a struggle and still not sure of these.... parsing greatly appreciated.
25a. Not out at cricket game's conclusion in Sicilian town (9) - AGRIGENTO (Sicilian town) I think it's NOT (anag. (out) ) + (gam)E but can't see the rest - or I could be completely wrong!
5d. Copy sent round half the world to unknown ministerial office (6) - CURACY (Office) Other than Y for 'Unknown' I'm at a loss.
12a. In a way, I do become a man (7) - RICHARD (I think) I can see 'Way' = RD but not the rest.
24d. Crossword editor to turn aside at last? Idle fellow! (5) D?O?E DRONE maybe but how and why?
