Wales beat Scotland in the Coral Scottish Grand National with last year's runner-up Kitty's Light getting the better of Cooper's Cross in a thrilling encounter.

Beaten by stablemate Win My Wings in the Ayr showpiece 12 months ago, the Christian Williams-trained chaser is still only seven yet has been running in these big handicaps for the past three years.
