I'm not sure the NBH stuff is a red herring - the motivation for bringing this situation about is important. The question of who started it and why are key, and this will help establish where the truth is likely to be.
Whether NBH would breach confidence in a complaint is a potential red herring though, as the sorts of individuals that phone these helplines are likely to be nervous and sensitive to the fundamental breach of trust in the 'contract' that disclosure will be confidential. In addition Ann Widdecombe's comments clearly indicate that the charity performs a counselling function, and has I understand resigned her position.
As an aside, neither the CEO nor the patrons, under good governance, have the remit to alter the vision or mission of the organisation. Where the Chairman and Trustees are in this situation is very interesting...as is the Charity Commission's summary of the Charity... http://www.scribd.com/doc/27230168/nbh-overview
The whole situation is chaotic, although according to Tom Peters, someone is thriving on it...!
