Much like last week, I found this this to be pretty impenetrable in places, so no doubt everyone else will find it an absolute doddle!
Some of the definitions were quite opaque, but that's not to say that they weren't fair.
I still haven't completely parsed 6,3d but the answer is clear. Also, I did get hung up on 13d for a while but, once I'd changed the last letter, all became clear.
My COD is 25,23a, which I think is just excellent.
Thanks to Paul for a very good workout:-)
