Morgan Stanley’s deal-making machine in Europe is being refitted.

As part of the changes, Dieter Turowski will relinquish the reins as head of mergers and acquisitions for Europe, a spokesman said, confirming a recent internal announcement at the bank. London-based Turowski, who's been in the role since early last year, will become global co-head of Morgan Stanley's sprawling natural-resources group, which comprises oil and gas, metals and mining and power and utilities.
