Building Societies (Funding) and Mutual Societies (Transfers) Bill

I bring my hon. Friend back to the point that we would be dealing with two groups of members: the members of a mutual may be borrowers or depositors. In such cases, both the interest groups would be served. I cannot think of another group of people who would have locus standi by petitioning as my hon. Friend suggests. Will he say who they could possibly be?
