Rafael Moral Santiago departs SIX with immediate effect, the Swiss financial infrastructure group said on Tuesday. He had served as Head of Securities Services and as a member of the Executive Board for just over a year. SIX did not give a reason for his exit.
Marion Leslie will take interim charge of the Securities Services business unit. She currently leads Financial Information and also sits on the Executive Board. However, her interim role remains subject to the required regulatory approvals while SIX looks for a permanent successor.
