Wall Street and Toyko to collide as Jasjit "Jesse" Bhattal is appointed to Nomura's board

Several former senior Lehman executives, including Siggi Thorkelsson, head of equities in Asia, and Thomas Siegmund, co-head of fixed-income in the region, have already announced they would be leaving Nomura this month.

The move is among several management changes expected to be officially confirmed by Nomura on Wednesday, including the hiring of Phillip Lynch as chief executive of Asia who will continue to work closely with Takuya Furuya, the chairman of Middle East and Asia.
