One of the most senior partners in the northern operation of Alsop Wilkinson is leaving to join rivals Garrett & Co. Manchester-based corporate finance lawyer Tim Hamilton has given notice and expects to leave next summer after 11 years with Alsop Wilkinson. "I am looking forward to joining Garrett & Co," he said. "It will be a new opportunity and an exciting challenge." Nick Painter, managing partner of Garretts' northern operation, said: "Tim is well-known on the Manchester market. Any time we get an opportunity to take anyone like him, we do."
