Former CEO of the Central Remedial Clinic Brian Conlan has issued a statement confirming his resignation from the clinic.
Amid the news of his resignation, a spokesperson confirmed that he would not appear before a Dail Public Accounts Committee hearing this week, as anticipated by Taoiseach Enda Kenny.
Mr Conlan today issued a statement, hours after his resignation was announced, explaining that he was abroad for personal reasons in recent weeks.
He added that he handed in his resignation within one day of returning home to Ireland.
"I have recently been abroad on personal leave and was away when the issue of top-up payments in the charitable sector came to public attention," Mr Conlan said in a statement today.
"Within 24 hours of returning to Ireland I tendered my resignation with immediate effect."
"I believe that it is in the best interests of the Central Remedial Clinic’s (CRC) clients and staff that the new Chief Executive should not have any association with legacy matters at the CRC."
Last month, the CRC confirmed that money donated by the public was being used to top up salaries of well-paid staff.
The Central Remedial Clinic in Dublin said charitable funds raised by a separate company the Friends and Supporters of the Remedial Clinic was funding the controversial top ups.
The clinic’s former chief executive Paul Kiely was on a State salary of €106,900 before he retired which was supplemented with another €136,000 in privately donated funds.
The scandal outraged the public and parents of children with disabilities who use the service.
It also used public donations to top up the salaries of several other executives. Brian Conlan was a new appointee and was not receiving top-ups.
He explains that he was appointed just five months ago and believes in 'full transparency' when charitable funds are concerned.
"I was offered the position of Chief Executive in July following a selection process conducted by the Board of the CRC with assistance from recruitment consultants Amrop Strategis. My salary as Chief Executive was within the guidelines provided by the HSE," he added.
"I had been in the position of Chief Executive of the CRC for a little over five months during which time my primary focus was on preparing the organisation for the anticipated bringing into force of the Charities Act legislation.
"I believe that there should be full transparency within the charitable sector with regard to how all funds raised, both private and public, are spent and that all executive remuneration should be within HSE guidelines.
"I hope that the CRC will now take the opportunity to start afresh with a clean slate so that the excellent service provided by its dedicated staff can continue to be made available to its’ clients who rely on it and who should not be the innocent victims of any fallout."
