It shows how confusing the whole issue is, but to train for a TMG Class rating which cannot be put on a NPPL, the instructor must be a UK or JAA FI with TMG rating. Article 101 applies.
Training for a SLMG rating can only be conducted by a MGIR at specified aerodromes in accordance with a blanket exemption to article 101, issued to the BGA.
The exemption does not permit training for a JAA licence or rating.
