The Public Accounts Committe wrote to Rehab earlier today calling on Frank Flannery to appear before it.

Fianna Fáil’s John McGuinness, PAC chairman, said he still expected him to “co-operate fully” with the parliamentary watchdog and to give evidence in the coming weeks.

“The position of the Committee in respect of Mr Flannery has not changed and, like the former board members at the Central Remedial Clinic, I expect that Mr Flannery will want to appear before the Committee to clarify issues in relation to the Rehab Group,” he said.

Mr Flannery’s evidence would be “central” to its inquiries which began with a cross examination of Ms Kerins and other senior Rehab figures last month, Mr McGuinness said.

“It was clear during that meeting that the witnesses present were not in a position to fully answer the questions of the (PAC) members and, therefore, a second opportunity will be available to Rehab to answer questions on areas such as remuneration, the involvement of Rehab with Complete Eco Solutions Limited — a company in which Mr Flannery was a shareholder — and in relation to the expenditure under the charitable lotteries fund,” he said.

“The committee expects to receive a comprehensive set of documentation in the coming days from Rehab and the committee will consider that documentation at its meeting on Thursday, March 13th.”

Mr McGuinness said other revelations about Mr Flannery over the past week will also have to be dealt with.
