Thanks for the 15d hint, perhaps not the greatest clue if so many of us were satisfied with a different answer. I found this generally easier than last week but struggled with 16d , my LOI, and 12a. I still don’t understand 16d and 12a seems a bit loose.
Thanks Everyman and, II suppose, Tortoise, for the puzzle, although as a digital subscriber to the Guardian, I’d have felt aggrieved if I’d lost access to what I thought I was paying for
