My questions have really been asked by Senator Fitzpatrick. I am just wondering how this will work from a practical perspective. Is someone allowed to be both a witness and a member of a committee? Is Deputy Ó Broin planning to act in both capacities or will he recuse himself as a member of the committee for the purpose of today's meeting?
