Thanks to Everyman. Agree with jono's opening post, quick solve but enjoyable (his other points as well).
FOI 4, LOI 25. My COD candidate list had seven clues, will award shared COD to 14, 21 and 23.
Needed Google to confirm my guess for 13.
Relatively large number of hiddens IMO. Off-topic ramble: I was once a regular Times cryptic solver, but haven't tried one in ages (quit when they went subscription-only)...Back in the day, I got the (possibly mistaken) impression the Times had a (tacit?) rule of a maximum of one hidden per puzzle.
