L. F. Rothschild Holdings Inc. said it plans to close virtually all of its securities operations in Britain and will lay off about 55 employees. The reduction will end the U.S. firm’s London activity in Eurobonds, British government bonds and U.S. Treasuries, leaving the firm with 10 traders and support employees charged with maintaining Rothschild’s own debt and equity accounts.
