US fund manager AllianceBernstein is on the look-out for a new head of its client group for Europe, the Middle East and Africa, following the departure of the former regional head of the group earlier this year.

The $486 billion investment house said Robert Keith, global head of the client group, has stepped in as interim Emea head with a search underway for a permanent replacement for Tim Ryan, who left at the end of January, according to the Financial Services register.
