Last Fianna Fail Mahon resignation
The last remaining Fianna Fail member named and shamed in the Mahon findings has quit the party.
Finbarr Hanrahan, a former councillor in Dublin, joins the likes of Bertie Ahern and Padraig Flynn by quitting before they could be expelled.
A Fianna Fail spokeswoman said: "We can confirm that Finbar Hanrahan has submitted his resignation."
The party's national executive will meet on Friday evening to discuss the Mahon report after motions to expel members were put forward.
The meeting will focus on restructuring the party's organisation in Dublin Central, once the most efficient electoral machine in the country.
Three-time taoiseach Mr Ahern was the first to walk away from his lifelong membership, before ex-minister and European Commissioner Mr Flynn also resigned.
Others to have quit include former TD GV Wright, former senator Don Lydon and sitting councillor John Hannon.
The transfer of branch assets in Dublin Central, including the famed St Luke's constituency office, will be on the agenda on Friday.
Meanwhile, a three-day debate on the devastating Mahon findings is under way in the Dail.
The inquiry into political corruption and the planning process shamed a series of senior figures in Fianna Fail, for decades the dominant, establishment party in Irish politics.
