Yes, Tatters, I tried an few anagrams of the title too but still nothing has come to mind. I'm inclined to think that this is a GWIT from Gwyneth Gwitty of Gwitterton, Gwent.
Just for the record, the only reason I don't show appreciation for your uploads is that as an expat, I signed up for the Times site some while ago and therefore don't need them. But it's kind of you to provide the puzzles for those who are unable to get them in these dire circumstances, and I certainly have no truck with the opinion of the sanctimonious twerp who had a go last week!
