Biffo clearly has to go, and soon. He's a perfectly decent guy but he's just not up to the job. Brian Lenihan would be his obvious successor were it not for the fact that he's battling a serious illness. Michael Martin would be the next obvious choice but he has just suffered the worst imaginable bereavement and I doubt very much if he wants to take on the job at this time. Which leaves Dermot Ahern and Mary Hanaffin as the only other obvious contenders. Or is anyone aware of a dark horse?
