This was found in grass next to a hedgerow next to a very busy road
No interactions present.
These are great pictures by the way.
I'm no authority, but I think it could be Ichneumon sarcitorius.

I agree - excellent pictures, no blurred edges!
Thanks for the comments, I've updated the title
Gavin Broad at the Natural History Museum says that this is indeed Ichneumon sarcitorius, so well done on the ID!
