Credit Suisse Group Tuesday said the head of its private banking arm in the UK, Ian Marsh, is stepping down, after just over two years heading the unit.

A spokesman for the Zurich-based bank declined to elaborate. Marsh, a former investment banker and 22-year veteran of Credit Suisse who formerly spearheaded efforts to link the three bank units more closely, including setting up a system to reward bankers who refer business to other Credit Suisse units, couldn't immediately be reached for comment.
