The FSA has fined Jo Malins for (pretty flagrant) market abuse. He has resigned from a couple of companies where he was a director but Cambrian Mining have refused his resignation and he is still a director at (IIRC) two others.
One of the papers said the FSA have invited the Nomads for those three companies in, to tell them why they still think Malins is a fit and proper person to be a director.
Obviously a different issue to Langbar, but a current example of how the FSA views Nomads as being pivotal to proper regulation of AIM.
