Hi all, this is my first post on here, though I've been turning to you all for help for a long time! So, many thanks for that. I'm baffled by 22a, my LOI. Assuming all the checkers are right, there is only one answer it can be, but I can't even see where in the clue the definition is, let alone parse it. As no-one else has mentioned this clue, I'm obviously being a bit dense!
