Maybe I'm just having a reaction to my Covid jab but I was all over the place on this one and really wasn't on Philistine's wavelength.
That's not to say it isn't well-clued but just that I struggled to see some of the definitions.
23d is a case in point where, although I'm confident of my answer, I can't see where "gang" fits in - in fact, if it wasn't for the cross-referenced clue at 8,26, I'm not sure I would have got it.
27a is another where I can't account for the middle 3 letters, although again, I'm confident of my answer.
FOI was 11,20 followed by 21d.
If you do get stuck there's long anagram in the acrosses and another one in the downs, though neither are straightforward - there's also a well signposted hidden in the downs.
COD - I've gone for the short but sweet 17a - Fish supplement pawned - excellent:)
I was pleased to see we had more new posters join our friendly Guardian Prize blog last week - the more the merrier 😉
Remember, if you get stuck you can always ask for a hint.
Thanks to Philistine for a well constructed puzzle.
