Magnenat, who will continue in his roles, will also take on additional responsibilities, a spokesperson for the Swiss private bank said when asked about the matter. 

Magnenat will become Lombard Odier Investment Managers’ UK CEO, subject to regulatory approval, and head of wholesale business in  the UK, Switzerland and Italy. 

A limited partner at the group for more than 12 years, he was also appointed to the LOIM executive committee in January this year as head of LOIM Asia.

The role of Duncan MacIntyre, limited partner and global UK region head, is unaffected, the spokesperson said.
