The Children's Investment Master Fund, a shareholder of London Stock Exchange Group, is standing by its resolution calling for Chairman and Director Donald Brydon to be removed, TCI said in a letter to the LSEG board of directors seen by Pensions & Investments.
"There is no change to our position on this," Christopher Hohn, manager and founder of TCI, said in the letter.
"The requisition ordinary resolution to remove Donald Brydon as a director of London Stock Exchange Group should proceed to a general meeting by no later than Dec. 28," the letter said.
The exchange said in a regulatory statement on its website on Wednesday that Mr. Brydon did not intend to stand for re-election at the annual general meeting in 2019. The exchange expected The Children's Investment Master Fund to withdraw its demands, first made Nov. 9. A spokeswoman declined to comment about TCI's letter on Thursday.
TCI simultaneously withdrew its position to cease the search for a new CEO, while permitting Xavier Rolet to remain in office until 2021 after Mr. Rolet left on Wednesday. He was replaced by David Warren, chief financial officer, on an interim basis.
