I appreciate that it cuts across a number of areas but who heads it up in the bank? Is there a clear division? If I am interested in entering the Irish market as a mortgage provider, is there somebody within the Central Bank that would be responsible for my application to see it through from start to fruition? Who is the senior person responsible for that?
