Rehab will provide more open and detailed information about the running of the charity before a key meeting of the Public Accounts Committee on Thursday, according to a Fine Gael member of the committee.

Fine Gael TD John Deasy said he expects a "change in direction" from Rehab ahead of the meeting.

He said that it will be more forthcoming with information being sought by the PAC.

Mr Deasy said former chief executive Angela Kerins and former director Frank Flannery owed it to Rehab and the charitable sector to explain what had gone on.

He said the sector did not need another "gun-fight" in committee rooms. 

"I think there will be a change of direction when it comes to imparting information and I expect that that will occur before the meeting and at the meeting" he said.
