Harry Cobden smuggled Captain Cody into the Coral Scottish Grand National to pinch its £112,540 first prize from Klarc Kent. While the ice cool ride was agony for backers of the runner-up, it was ecstasy for all-conquering who saddled both.
The top result - a week after a 1-2-3 in the English version - puts him within touching distance of a second British trainers' title.

Meanwhile Cobden - a reigning champion of the jumping game like the Irish handler - was biding his time in rear and plotting a path to the front.

Kept widest of all, it soon became clear to observers that he had found the key to Captain Cody, who showed off an impressive gear change to pass Klarc Kent on the run-in.

In a rapidly-changing renewal, which saw fellow Mullins hope Spanish Harlem carried out by Walking On Air, only eight horses completed the course.
