All done. Thanks Rog. Got 25d straight after last post then 25a was LOI and a great clue in fact. 5d was the only weak link as I feel the abbreviation is a bit off in order to make the clue work. And I'll not mention 10a for obvious reasons.
Thanks to Brockwell as ever for a fine workout.
FOI was themed 8a. COD, there are many, but I'm going for 30a.
