My simple mind sees no difference between your employer sending you on a PPL course, a computer course, a (god forbid) MBA course or even a tiddly winks course. For that matter any 'in-house' courses fit into the same pot.
As a course is designed to assist employees to contribute to the fortunes of the employer and therefore directly related to their employment it is A/a tax deduction (expence)for the employer B/ for the ultimate benefit of the employer and C/ nobody else's business.
Like I said, I have a simple mind.
