I'm sorry if I am missing the point but surely you do have a legal aid solicitor?
Well, that is fairly normal I'm afraid. You are not charged so there is no disclosure from the Crown. Therefore his view will be that that is nothing to discuss and anyway he is not paid for doing it. In fairness, solicitors cannot be expected to work unless the Government pays them or they charge privately.
You can instruct another solicitor when charged.
Or you can pay privately.
On the whole though it is not a good idea to be agitating the police. Generally speaking, you do not want to make contact with them and remind them of the need to do work on your case.
Can I clarify anything for you?
