The reshuffle at Russell Investments, revealed this month in Financial News, has now reached the boardroom with the replacement of Andrew Doman as chief executive by Len Brennan, brought in just a month ago as European head.

Doman, who was appointed at Russell only two years ago, will become chairman of the board of directors. Ed Zore, who has chaired Russell's board since 2008, will remain on the board as a director.
