All finished, and I thought that this was the easiest we've had for a while. However as is often the case I have a couple of stubborn loose ends that need tidying up. Please can someone put me out of my misery and explain the following:
1. Where the first letter of the answer to 15d come from? I can parse the rest of the wordplay but not that letter.
2. Similarly for 19d I don't see where the first two letters of the answer come from.
Thank you in advance!
