Low salt lamb stock?

[AngelDog]

Anyone know where I can get low-salt lamb stock (other than by making my own)? We do like a lamb casserole but I don't want to give DS lots of salty stock. It's just not the same with veg stock.

The Boots Organic range does low salt stock cubes Not sure if they do lamb, but they defintely do chicken, would probably be nicer than veg stock.

I'm looking for lamb too. At the moment, I'm using Boots beef stock, and adding extra herbs.
