Fried Frank Harris Shriver & Jacobson’s structured finance head, Larry Isaacson, has quit to lead a team of lawyers to Ernst & Young’s US law practice McKee Nelson in a major blow to the New York firm.

Isaacson, who is Fried Frank’s head of structured finance and securitisation, left the US firm with fellow partner Andrew Kwok to join McKee’s New York arm on Wednesday (25 June).
