Chairman of the Public Accounts Committee John McGuinness has called on Frank Flannery to come before the committee following newspaper reports about his lobbying efforts on behalf of the charity Rehab.
It's understood that Rehab will finalise a comprehensive submission for the Public Accounts Committee early next week, following which it's expected that Mr Flannery will address any outstanding issues.
Newspaper reports suggested that the Fine Gael party strategist had been paid by Rehab to lobby the Government on its behalf.
Mr McGuinness said it was unacceptable that Mr Flannery had not yet appeared before the PAC.
He added that these latest developments were undermining the whole charity sector.
