JPMorgan Chase may move hundreds of its staff from London to its offices in Dublin, Frankfurt and Luxembourg following Brexit. The bank said it is going to use the three banks it already has in Europe as the anchors for the operations. It confirmed it will move people in the short term to be ready for day one, when negotiations finish, and then it will look at the longer-term numbers. JPMorgan chief executive Jamie Dimon told UK employees that as many as 4000 could be relocated in the event of Brexit.
