London Stock Exchange Group shareholders are to vote on whether to hasten chairman Donald Brydon's exit following investor anger at the departure of chief executive Xavier Rolet, the LSEG announced.

In a letter sent to shareholders Thursday, the LSEG board said a general meeting would take place in London on December 19, where investors are invited to vote on whether Brydon should be "removed from office as a director of the company with immediate effect".

It comes after British activist investor The Children's Investment Fund, which holds around five percent of the LSEG, demanded his removal.

The LSEG on Wednesday announced that Brydon, who is accused by TCI of forcing Rolet out in a reported boardroom struggle, will not stand for re-election in 2019.
