Hey tonyblair,
As far as I can see, the beauty of this sponsorship arrangement is if your sponsor went bust during training, you'd just be back in CTC-McAlpine's pot. Sounds pretty safe to me.
Yup I know where you are comming from. Just thinking that if they consider it a loan then you would wind up as a debtor in such a case. I think I am stretching the argument a bit far here I know

But until you see the small print

It is one hell of a lot of wonga!
Cheers,
Kef.
