(Adds comment from victims group)
By Philip Pullella
VATICAN CITY, Feb 6 (Reuters) - A prominent British member of a papal advisory commission on sexual abuse by the clergy who has been outspokenly critical of the Vatican has left the group, the Vatican said on Saturday.
A statement said that at a commission meeting "it was decided" that Peter Saunders would take a leave of absence. Saunders, head of Britain's National Association for People Abused in Childhood, would now "consider how he might best support the commission's work".
In a separate statement, commission president Cardinal Sean O'Malley of Boston said Saunders had been asked to advise the commission on the possible establishment of a victim survivor panel.
Saunders, a victim of sexual abuse by a priest, did not immediately reply to a telephone message requesting a comment.
His departure leaves only one victim of sexual abuse by a cleric, Marie Collins of Ireland, sitting on the commission, which has been slowed down by internal disputes.
Saunders had been increasingly critical of the commission, which was set up in 2014. Made up of clerics and lay people from around the world, its task is to help Pope Francis establish "best practices" in dioceses around the world to root out sex abuse in the Church. Eight of the 17-member commission are women.
The U.S.-based Survivors Network of those Abused by Priests said it shared Saunders' frustration with Vatican officials.
"Pete has been a brave, honest and tireless voice for kids and victims," it said in a statement.
On the eve of the current meeting, Saunders was quoted by the Los Angeles Times as saying that the previous meeting last year was a "non-event," and demanded that the pope attend the current meeting.
"It will be outrageous if he doesn't attend, and I will say so - it will be the end of the honeymoon for Pope Francis," the Los Angeles Times quoted him as saying.
In a worldwide sex abuse scandal, which first became prominent in Boston in 2001, abusers were shunted from parish to parish instead of being defrocked and handed over to authorities.
Saunders has been spoken out on several issues in the past few months. Last year, he criticised Francis for appearing to endorse parents who spanked their children in order to discipline them. also made waves when he said that Australian Cardinal George Pell should be dismissed over allegations he failed to take action to protect children years ago. Pell is now the Vatican's economy minister. ID:nL3N0YN2JJ .
Last April, Saunders and three other lay commission members met with O'Malley to complain over the over the appointment of a bishop in Chile accused of covering up abuse. Vatican says that as part of an advisory body, the commission's members should not comment on individual cases of abuse and leave these up to investigators.
