As always, a neat and pleasant crossword from Phi, with not a superfluous word so far as I can see (except perhaps in 4dn). I can’t quite see 16dn, but no doubt there will be plenty of suggestions.
Yesterday’s plea for fewer Ninas and more vanilla crosswords seems to have been answered very quickly. But a) if it is Nina-free then this is obviously a coincidence and b) I expect it isn’t really Nina-free. It seldom is with Phi.
Definitions underlined.
