The Charities Regulator has confirmed it is aware of concerns related to corporate governance at Patient Focus.

In a statement to RTÉ Investigates the Regulator said it is to engage with the patient advocacy service regarding these concerns.

Last week RTÉ Investigates learned the Health Service Executive is working with the charity to address some corporate governance issues.

It also emerged that all current board members, bar one, have resigned from the charity.

This afternoon, a spokesperson for the Charities Regulator said the body was aware of the ongoing situation at Patient Focus.

They said: "We will be engaging with the charity to ensure it is meeting its obligations under the Charities Act in respect of management and control of the charity."

RTÉ has made several unsuccessful attempts to contact Patient Focus for comment.

The charity, which was founded in 1999, rose to prominence at the time of the Dr Michael Neary caesarean hysterectomy scandal in Drogheda, Co Louth.

At that time Patient Focus supported more than 100 women who underwent unnecessary operations at the hands of the disgraced former obstetrician and gynaecologist.

It has since provided support to hundreds of other patients and their families affected by some of the country's most high profile healthcare controversies.
