Unfortunately is seems that our MP's are severely confused. It would appear from the reply I received, from Russell Brown, and from what publicity I have seen, BBC breakfast TV. The general concensus, including that of the MU according to BBC, is that the new laws are going to make things better by doing away with the two in a bar and making everything much simpler and clearer for both publicans and musicians.
Until this misconception is corrected I fear theres not much to be done. At the moment any referall about this seems to elicit the response- we're fixing it with our new law.
