British Prime Minister Theresa May has admitted she knew there was some tension between former New Zealand High Court judge Dame Lowell Goddard and the panel she led on the UK child sexual abuse inquiry.
Today during the Prime Minister's question time in the British parliament, Mrs May was asked when she learned there was a serious problem and why she didn't take action.
At the time Mrs May was the Home Secretary. She said she had heard there was tension weeks before official concerns were raised but she was unable to act on "suspicion, rumours and hearsay".
Yesterday a British parliamentary select committee heard that the panel had found working with Dame Lowell "challenging" and they "had concerns about the qualities of leadership that were being evidenced during the course of the inquiry".
Dame Lowell resigned in August after 16 months as chair of the inquiry.
By law the Home Secretary cannot intervene unless there is clear evidence of wrong doing or some kind of official complaint.
During the select committee hearing one of the panel members said she had told a general manager in the Home Office about her concerns but it wasn't official.
Labour MP's are saying it looks like a cover up.
The select committee has asked Dame Lowell to give evidence and are willing to arrange a video link from New Zealand. It's unknown if she has agreed to either request.
