Hi Brendan
These are my last two as well. No, I lie. I have to get 27ac as well, which must be a special.
Your hint for 2d is 7 letters long, but the answer is only 6 letters. I've just got it - an unusual word for increase.
I think I have 9ac now, though I can't parse the original answer. (I've just seen it as well).
I think I have 27ac now. I just realised it had to be my last themed one.
So, I've finished. I heven't been able to parse 20d, though my answer fits the definition.
I've really enjoyed this crossword as I actually managed to solve most of it on my own. FOI 11ac, LOI 27ac COI 22ac, 16d and 10ac and a number of others.
