Fianna Fáil leader Micheál Martin has said that there is anger within the party in relation to bad behaviour by some members in the past, particularly in relation to fundraising.
Mr Martin was not specific in referring to any particular member of the party, but said that there is a need for Fianna Fáil and all other parties to do things differently in relation to fundraising, including a ban on corporate donations.
He said, however, that there was no evidence of that reform coming.
Arriving at the MacGill Summer School in Glenties, Co Donegal, where he is addressing the topic of political reform, Mr Martin said there needs to be a stronger separation between parliament and executive.
He said there was a need for radical change of political architecture, so that members of government should not be members of the Dáil for the duration of membership of government and the Taoiseach should have the capacity to appoint people from outside parliament to government.
Questioned about former Taoiseach Bertie Ahern, Mr Martin said he would not pre-empt the finding in the Mahon Tribunal, but there was anger in the party in relation to what emerged in evidence and there was a clear mood in the party that things would have to be different in the future.
In relation to the upcoming Presidential election, he said Fianna Fáil would decide on the issue in September.
