Thanks, Kite.
I've been sapped by hot weather this week, which decreased motivation. Fun solve but rather gentle. The expected theme quickly revealed itself. About 3/4 of the grid was a write-in, but there were a few toughies. Needed Google for 22, 23 and 17 (I'd seen the latter word but it didn't jump to mind).
Being American, I was rather chuffed to solve 11 from wordplay
sans Google assistance, though the crossers were a big help.
FOI 1a, LOI 11.
Not many clues stood out. COD candidate list 11, 16, 18, 21 and 25. The nod goes to 25 because I like the tricky wordplay device; solved it quickly because a similar clue appeared in last week's Prize (8d).
