Good afternoon Torvic & Navigator,
You two have come scorching out of your blocks this week and, having read your comments, I totally agree with what you've both said
except 11a. As this was the last answer which I put in, you'll appreciate that I could work out the answer from the checking letters and then, when I looked at the clue, I thought, "What an ugly construct!"
With kind regards,
