The Football Association has announced that its review into child sexual abuse in football will be led by Clive Sheldon QC instead of Kate Gallafent QC in the light of its "increased scope."
The FA had initially appointed Gallafent to oversee an internal review into allegations of sexual abuse made by former players but said "a wide-ranging inquiry may be required in time."
That time appears to have arrived sooner than expected with the scale of the situation growing by the day, and Gallafent has been replaced "with respect to her other professional commitments."
In a statement, the FA noted that Sheldon's past work included several investigatory reviews including on matters of child protection and safeguarding.
The news came as the FA outlined the full terms of reference for its review, which has been launched with no firm deadline -- a result of the passage of time since the alleged abuse.
"The review will commence immediately," the organisation said. "The findings of the review will be reported to the FA board. It is accepted that no final date can be agreed at this stage.
"The precise number of players, alleged abusers and clubs as yet is unknown.
"The FA continues to work closely with the relevant authorities and respects the ongoing investigation by the police being coordinated by Operation Hydrant into childhood sexual abuse in football."
The Sheldon investigation will cover what was known, and the actions that were taken, by the FA from the 1970s to a nominal end point of 2005.
The actions of individual clubs, from elite level to grassroots, will also be assessed and their subsequent actions considered.
The statement added: "In the event the review finds such steps to be lacking, the review will look to extend its scope."
