Xavier Rolet, CEO of the London Stock Exchange Group, has left, said a statement Wednesday.
David Warren will become interim CEO in addition to his current role as chief financial officer until a successor is named, LSEG said in the statement. A spokeswoman declined to provide further details. Mr. Warren has been CFO since 2012.
The exchange said Oct. 19 that Mr. Rolet would leave by the end of 2018. But a resolution was put forward by LSEG shareholder The Children's Investment Master Fund on Nov. 9 calling for Chairman Donald Brydon to be removed instead, and for Mr. Rolet to be permitted to remain in office until 2021.
Mr. Brydon does not intend to stand for re-election at the annual general meeting in 2019, LSEG said in a regulatory statement on its website Wednesday. The exchange also expects The Children's Investment Master Fund to withdraw the resolution by Nov. 30. TCI could not be reached for comment.
Mr. Rolet said in the release: "Since the announcement of my future departure, there has been a great deal of unwelcome publicity, which has not been helpful to the company. At the request of the board, I have agreed to step down as CEO with immediate effect."
Mr. Rolet will spend 12 months on garden leave. He confirmed he had no intention to return as CEO or a director of the exchange.
