HSBC's former co-head of global investment banking, Robin Osmond, has left the bank following a shake-up of his division last month which left him looking for a new position. His fellow co-head, Mark Bucknall, exited as part of the reshuffle. It is unknown where Osmond will go.

Osmond was understood to be in discussions with HSBC about taking a different position but then decided to leave, according to sources close to the bank.
