Lawn Tennis Association president Martin Corrie has "stepped aside" amid an investigation into the way a committee he was on dealt with a sexual assault allegation.
Corrie has been replaced temporarily by deputy president David Rawlinson.
In a statement the LTA acknowledged it had commissioned an investigation following a complaint made in December relating to an allegation from 2004.
Corrie had served on the committee that addressed the original complaint.
He said: "This case concerns a coach who worked at Hertfordshire County LTA when I was a member of the executive committee, who was investigated and sanctioned by the LTA disciplinary committee at the time.
