Micheál Martin (Cork South Central, Fianna Fail) | Oireachtas source

-----but our Constitution could not be clearer. Each Member of this Dáil carries a mandate for a full term, and the choice of all office holders can change throughout this mandate. I confess that I have been amazed by the brazenness of the largest Opposition party on this matter, given that "I will be seeking support at the Sinn Féin convention" has long been one of the emptiest and most meaningless phrases ever uttered. Of relevance today is that while it is attacking the democratic legitimacy of this vote, the party in question has a unique record of privately appointing and replacing leaders without ever holding an internal election let alone a public one.
