Two more senior investment bankers have left Morgan Stanley in New York. Jane Wheeler is joining Evercore Partners, an advisory boutique, and James McGinnis is joining AIG Financial Products, the investment banking arm of US insurer American International Group.

Their departures bring the number of senior departures at the US investment bank to at least 16 in the four months since a group of dissident shareholders started a campaign to oust Philip Purcell, chairman and chief executive, who resigned last month.
