Steve Phillips has resigned as chief executive of Welsh Rugby Union after claims of misogyny, sexism, racism and homophobia were levelled at the organisation.
He had previously resisted calls to quit after the broadcast of a documentary, which heard accusations of a “toxic culture” at the game’s governing body in Wales.
A number of former employees took part in the investigation by BBC Wales.
Charlotte Wathan, general manager of women’s rugby until her resignation last February, spoke of how a male colleague said in front of others in an office that he wanted to “rape” her, while another unnamed contributor says she was left contemplating suicide by her experiences of bullying and sexism at work.
In response, WRU chair Ieuan Evans had announced the setting up of an independent taskforce to look into the allegations and examine “culture and behaviours”.
Phillips attended the meeting about the move, but had since decided it was “time for someone else to lead the way”,
He said in a statement: “It is with a huge amount of regret that I have decided to hand in my resignation.

“I have always had the best interests of Welsh rugby at the heart of my every action and thought, but have come to the conclusion that it is now time for someone else to lead the way.”
He added: “I am on record already saying how much I hugely regret the feelings and emotions expressed recently by former members of staff.”
Former Olympic hurdler and Wales wing Nigel Walker, who was the union’s performance director, will take over as acting chief executive with immediate effect.
