Worcester chairman and backer Cecil Duckworth says the prospect of a full-blown, top-flight Anglo-Welsh league is "worth looking at seriously".

"But in a couple of years or so time when those arrangements have to be renewed, or altered, or we change direction a little, then that's [an Anglo-Welsh league] a possibility, of course.
"I would have thought it would be good for us and good for Wales. I'm sure it would be something worth looking at seriously."
