Mike Weston, Morgan Stanley's London-based head of global head of debt syndicate, has resigned from the firm to take a break from the industry, according to a firm insider. The insider says Weston maybe interested in returning to his native New Zealand. His duties will be assumed by Raj Dhanda and Michael Heaney, who will serve as co-heads of global debt origination. They report to Walid Chammah, co-head of global capital markets. Previously, Dhanda had been head of U.S. head of debt syndication and Heaney was head of European debt syndication. A Morgan Stanley spokesman declined to comment.
