Goldman Sachs Group Inc. faces a regulatory probe in Britain and scrutiny from the German government after the U.S. Securities and Exchange Commission sued the firm for fraud tied to collateralized debt obligations.

Prime Minister Gordon Brown on Sunday called for the Financial Services Authority to start an investigation, saying he was “shocked” at the “moral bankruptcy” indicated in the suit. Germany’s financial regulator, Bafin, asked the SEC for details on the suit, a spokesman for Chancellor Angela Merkel said.
