Thanks to Everyman for a well-crafted puzzle.
I found the level of difficulty mid-range, fewer write-ins than usual but not many head-scratchers either.
There's a long anagram in the downs, which might help to get started.
I saw no rhyming pair, but heavy alliteration in the long clues, which Everyman sometimes employs instead. Most other Everyman regular features: first letters, homophones, foreign phrase.
FOI 7, LOI 5, though 1a (next-to-LOI) was the clue that mainly held me up.
Co-COD 11 and 18, runners-up 16, 1d, 10 and 1a.
One solution may not be familiar to non-UK solvers (incl. me), but the wordplay was sufficiently clear for parsing.
