Five U.S. investment banks promised British finance minister George Osborne on Thursday that they would try to help London keep its top spot as a financial center, but gave no commitment on jobs following Britain's vote to leave the European Union.

One banker at the meeting with Osborne told Reuters the banks wanted to see concrete moves to ensure firms based in London would retain access to EU markets, however, because "no one in their right mind" would currently invest in Britain."

If that's what "support" from US bankers looks like, I shudder to think what their wrath might be.
