Jessel leaves Principal Search

Mike Chilman, a director of the firm, said he was not certain of Jessel's plans for the future. His expertise includes origination, sales, trading and research functions for all equity-linked products.

Earlier this month Principal Search announced the hire of John Burr from the financial services practice at global headhunter Heidrick & Struggles, as its fourth director.

The other two directors are Nick Williams and Taru Oksman-Ison.
