Phew! Another very tricky crossword.
I think Paul used pretty much every device available to a setter to keep us all on our toes.
There are anagrams, both total and partial, homophones (these often cause much debate, and I don't think these will be any different) 'hidden' clues and, of course, charades - some of which are 'containment' type clues and are quite complicated!
There is a delightful reference to a Shakespeare play in one clue but I won't say which.
14a and 13d are very funny and have well disguised definitions.
I'm still not certain of the parsing for 20a and, as such, unsure which of 2 possible answers is the correct one.
9a also took quite a bit of working out, which is often the way with geographical clues - at least for me.
Thanks Paul for a difficult but well clued crossword.
