JPMorgan has told “several dozen” of its UK-based staff that they will move to other European cities in preparation for Brexit — with the bank having already warned that up to 400 jobs could shift on “day one” of the split.

Daniel Pinto, chief executive of JPMorgan’s corporate and investment bank, and Mary Erdoes, head of asset and wealth management, said in a memo seen by Financial News that those affected will move later this year or in early 2019, pending political and regulatory clarity.
