Thanks, Quisling, there have been several unsatisfactory clues on this thread recently, but this one really was the shoddiest. You're more generous than I am - you described the definition as 'sketchy', I'd simply class it as wrong! The surface reading was grim, the clue seemed just a collection of words strung together.
Bharat, I'm pleased that you feel you are learning things from the Forum. As a keen crossworder, I appreciate good, well-written clues - and am always disappointed when clues fall short, as some of these ones do.
